No action required.

06 DEMO PAGE

Printing a Demonstration Page. (Note that PCL/PostScript formats are different.)
No action required.

06 CONFIG PAGE Printing a Configuration Page. No action required.

07 RESET

Follows a control panel Shift + Reset selection. The printer returns all Printing, PCL, Job, and installed personality (PS, etc.) Menu items to user-selected settings and clears buffered page data, clears temporary soft fonts, and clears temporary macros.

No action required unless the printer is receiving data. You may have to press Shift + Reset several times to prevent printing unwanted pages.

08 COLD RESET

The printer returns all Printing, PCL, Job,Config, Mem Config, Parallel, MIO (if installed), and the installed personality (PCL, PS, etc.) Menu settings to their factory default configurations, except for page count, MP Tray size, and display language.

Reconfigure the printer and MIO. When you install an MIO card, to reinitialize the control panel you may need to perform a cold reset. (Note: In a shared environment, this task should only be performed by the system administrator.) To perform a cold reset, hold down On Line while switching the printer ON until 08 COLD RESET appears in the display.

09 MENU RESET

Clears the page buffer, removes temporary data such as downloaded fonts, and sets user-selected defaults (such as Power Save) to their factory defaults.

Reset the printer. There are two choices:

To immediately activate the selections, press Shift + Reset until 07 RESET appears (you will delete temporary macros, fonts, and buffered data).

Press Shift + Continue or On Line. Your changes will remain recorded in the menu (marked with an *), but will not become active until the printer is reset or the printer detects the end of the job.

12 PRINTER OPEN

The front door is not firmly closed, or the toner cartridge is not installed correctly.

Make sure the toner cartridge is fully seated and the front door is firmly closed. If the message persists:

The sensor flag for Front Door Open Sensor may be broken or stuck.

The toner cartridge microswitch may be broken or stuck.

The DC Controller PCA may need to be replaced.

13 PAPER JAM

Paper is jammed in the paper path, or a paper jam sensor may be stuck, causing a false paper jam warning. The jam rate specifications are:

MP TRAY: 1 per 6000

CASSETTE: 1 per 4000

NOTE: Many variables can affect actual frequency of jams. The above specifications are intended as a general guideline only.

Remove jammed paper (see "Clearing Paper Jams" in the User’s Manual). The front door must be opened and closed again before pressing On Line to resume. The following are the most likely causes of repeated paper jam problems:

Paper cassettes not correctly loaded (refer to the User’s Manual).

Print media does not meet specs or is in poor condition (refer to the Paper Specifications Guide).

The printer needs cleaning. Pickup, Registration or Output rollers contaminated, worn or damaged.

Toner cartridge gears are worn or damaged (try a different cartridge).

Other paper path gears worn or damaged.

If no paper jams are found but the message persists (false paper jams):

The paper jam sensor flags may be sticking or damaged.

The DC Controller PCA may need to be replaced.

14 NO TONER CART

The toner cartridge is missing or not installed correctly.

Insert a toner cartridge or make sure the cartridge is fully seated and the front door is fully closed, then press On Line to resume. If the error persists:

The toner cartridge microswitch may be broken or stuck. The sensor flag for Front Door Open Sensor may be broken or stuck.

The DC Controller PCA may need to be replaced.

16 TONER LOW

The toner cartridge is running out of toner. If TONER LOW=CONT* is displayed, the printer will continue printing; if TONER LOW=STOP, the printer will stop printing and go off line.

Shake the toner cartridge or replace it. If TONER LOW=STOP, press On Line or Shift + Continue to allow printing to continue (print quality will gradually degrade). If the message persists:

The contact points on the left end of the toner cartridge and inside the toner cartridge cavity (The Toner Low contact is the lower of the three) may be damaged or dirty.

The High Voltage PCA may need to be replaced.

18 MIO INIT The MIO card is initializing.

This is a status message; during initialization the MIO is not active, but since the printer supports I/O switching, the printer remains on line.

No action required. Display will clear automatically (this may take up to a minute, depending on the card). However, if the message remains after 5 minutes a problem may exist in the network card or host. Consult the network documentation that came with the MIO card.

18 MIO NOT READY

The MIO card is not ready. The Bi-Tronics parallel port will continue to operate normally.

If the printer MIO card is operating correctly and communicating with the network, this message will disappear after approximately one minute and no action is required. If the MIO card is unable to communicate with the network, this message will remain for five minutes and then go away. In this case the printer is not communicating with the network (even though the message is no longer present). The problem may be a bad MIO card, bad cable/connection on the network, or a network problem. Consult the network documentation that came with the MIO card.

20 MEM OVERFLOW

The printer received more data from the computer than can fit in its available user memory.

Press Shift + Continue to print the transferred data (data loss may result), then: make more memory available in the printer by removing some fonts, macros, or any other data from memory; or, simplify the page sent to the printer; or, install additional memory. (Note, if AUTO CONT=ON the printer will automatically continue printing when this error occurs).

21 PRINT OVERRUN

The data (dense text, rules, raster or vector graphics) sent to the printer was too complex.

Press Shift + Continue to resume printing. (Note, if AUTO CONT=ON the printer will automatically continue printing when this error occurs). Some data loss may occur. Try to simplify the print job. If you must print the job "as is," set PAGEPROTCT=ON in the Job Menu, print the job, then return PAGEPROTCT=AUTO. Do not leave PAGEPROTCT set to ON as it will degrade performance.

22 PAR IO ERROR,

22 MIO ERROR

Clearable Warning Messages

Message

Meaning

W0 JOB 600/A4

Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of A4.

W1 IMAGE ADAPT

The printer received a graphics print file that was too complex to print at the requested print resolution. Check the printout for loss of data or print quality. NOTE: If this warning occurs frequently, install additional memory.

W2 INVALID PERS

The job was not printed because you requested a personality, such as PostScript, that is not installed. Install the personality that matches the personality of the files you are sending, together with enough memory to support that personality.

W3 JOB ABORTED

The printer was forced to abort the print job because there is not enough installed memory to support the current printer language (PostScript, for example). Install additional memory.

WD DISK NOT INIT

The printer was unable to read the root directory from the disk. Use the disk initialization utility to initialize the disk.

W8 JOB 600/OFF

Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi and page protect was turned OFF.

W9 JOB 600/LTR

Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of LETTER.

WM JOB 300 The job was printed at 300 dpi. NOTE: if this warning occurs frequently, install additional memory.

WM JOB 600/A3

Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of A3.

WM JOB 600/LGL

Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of LEGAL.

WM MEM CNFIG N/A

The printer did not have enough memory when switched ON to support the previous settings for I/O Buffering and/or Resource Saving, probably because you removed a memory SIMM, or added a new personality SIMM. (You can check settings by printing a self test.)

WM CHK MEM CNFIG

I/O Buffering and/or Resource Saving settings were altered when the printer was switched on because the printer did not have enough memory. This usually occurs after memory has been removed from the printer. (You can check settings by printing a self test.) Adding additional memory should correct this problem.

If you switch the printer OFF, then ON, you may lose settings. (To check settings, print a self test). If the error persists, the Formatter PCA needs to be replaced.
70 or 71 ERROR	A language (personality) SIMM problem was identified. SIMM not compatible with firmware.		Remove or replace the language (personality) SIMM.
79 SERVICE [xxxx]	A Formatter firmware error occurred. The numbers [xxxx] following the error indicate the specific kind of error.		Switch the printer OFF, then back ON. Remove SIMMs one at a time and recycle power to isolate. If the problem persists, and the printer has an MIO card installed, remove the MIO and try using the parallel interface, if possible. The Formatter PCA will need to be replaced.
80 SERVICE [xxxx]	The printer detected a problem in the MIO card. The numbers [xxxx] following the error message indicate the specific type of error.		Switch the printer OFF, then back ON. If the error persists: Remove and reseat the MIO card. Check for bent pins on the MIO connection. Replace the MIO card. The Formatter PCA needs to be replaced.
FS DISK FAILURE	Printer detected a disk failure. Printer operation may continue, provided access to the disk is not required. (The printer will substitute fonts if necessary.)		Press Shift + Continue, to continue printing when this error occurs. Switch the printer OFF and then back ON. If the error continues: Remove and reseat the disk drive, ensuring that the connector pins are fully seated in the connector on the Formatter PCA. Run a control panel self test to verify presence of the disk drive (look for the text, "Installed options: Disk"). If the error persists, replace the disk drive.
MENUS LOCKED	The network administrator has locked out access to the control panel menu system, except for the Test Menu and MP Tray size.		See the network or printer administrator.
ME FEED envelope size	The printer requested that an envelope be manually fed. Envelope size may be: COM10, MONARCH, DL, C5, B5, JPOST, or JPOSTD.		Insert the appropriate envelope size into the MP Tray and press On Line or Shift + Continue if MP Tray is not in "first" mode to print from the envelope feeder.
MF FEED paper size	The printer requested that media be manually fed. Paper size may be: LETTER, LEGAL, A4, EXEC, 11x17, A3, JIS B4, JIS B5, CUSTOM.		Insert the appropriate paper size into the MP Tray and press On Line; or, press Shift + Continue (if the MP Tray is not in "first" mode).
MP LOAD, PC LOAD, or LC LOAD paper size, or envelope size	The printer received a request for a paper or envelope size not available in the printer.		MP LOAD: Load MP Tray with the requested media. If the size is not selected in the printer control panel, use the MP Paper Size key to enter the requested size, or press Shift + Continue to draw the requested size from another source, if available. Note: If MP LOAD remains in the display, you may have to clear the buffer by resetting the printer. Press Shift + Reset. PC or LC LOAD: Load the Paper Cassette or Lower Cassette with the requested media. Also, the back paper guide in the cassette must be set to the correct media size (the printer determines the media size by reading the location of this guide).
Clearable Warning Messages
Message		Meaning
W0 JOB 600/A4		Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of A4.
W1 IMAGE ADAPT		The printer received a graphics print file that was too complex to print at the requested print resolution. Check the printout for loss of data or print quality. NOTE: If this warning occurs frequently, install additional memory.
W2 INVALID PERS		The job was not printed because you requested a personality, such as PostScript, that is not installed. Install the personality that matches the personality of the files you are sending, together with enough memory to support that personality.
W3 JOB ABORTED		The printer was forced to abort the print job because there is not enough installed memory to support the current printer language (PostScript, for example). Install additional memory.
WD DISK NOT INIT		The printer was unable to read the root directory from the disk. Use the disk initialization utility to initialize the disk.
W8 JOB 600/OFF		Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi and page protect was turned OFF.
W9 JOB 600/LTR		Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of LETTER.
WM JOB 300		The job was printed at 300 dpi. NOTE: if this warning occurs frequently, install additional memory.
WM JOB 600/A3		Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of A3.
WM JOB 600/LGL		Because the job parameters of print resolution and page protection could not be met with the available memory, the job was printed at a print resolution of 600 dpi but reduced to a page protect setting of LEGAL.
WM MEM CNFIG N/A		The printer did not have enough memory when switched ON to support the previous settings for I/O Buffering and/or Resource Saving, probably because you removed a memory SIMM, or added a new personality SIMM. (You can check settings by printing a self test.)
WM CHK MEM CNFIG		I/O Buffering and/or Resource Saving settings were altered when the printer was switched on because the printer did not have enough memory. This usually occurs after memory has been removed from the printer. (You can check settings by printing a self test.) Adding additional memory should correct this problem.
