Cartridge error messages
Paper jam error codes (200-series)
Note:  The Event log (see “EVENT LOG” on page 3-28) will list any of these errors that have occurred.
Repeating jams or jam messages can be caused by any of the following:
•Faulty/contaminated pick solenoids or worn cams of the solenoids.
•Faulty/contaminated flags or springs.
•Debris in the paper path.
•Media not of the specified length. Error Description
31 Defective cartridge
32 Unsupported print cartridge
33 Invalid refill
Paper jam error codes (200-series)
Error Description
200.00 Paper jam around input sensor.
200.01 Classic input jam. The media is too long over the input sensor. Possible causes include multi-sheet feed, tray 
size sensing problem, and media slippage.
200.02 The main input sensor never became uncovered from the sheet ahead.
200.03 The video never started on the page at the input sensor within two inches after hitting the input sensor
200.04 The media at the input sensor before interrupt occurred - not enough time elapsed since the printhead started 
to expect the printhead mirror motor lock. Possible causes include bouncy sensor or exceptionally fast pick - 
perhaps due to media pre-staged in the source tray.
200.06 Imaged page not expected page (bouncy passthru sensor)
200.08 Media reached the input sensor before the EP was ready
200.09 Transfer servo never started
200.12 Media detected at manual feeder sensor when not expected. Possible causes include user insert of media 
when motor is running or pre-staged media in the tray.
200.13 The input sensor is covered when the media is not expected (media in machine during warm-up)
200.14 Trailing edge cleared manual feed, but did not successfully debounce the sensor. Potential causes are a small 
gap or a bouncy manual feed sensor.
200.15 UNRECOVERABLE NO GAP JAM. Engine detected no gap at the manual feeder sensor, attempted to open 
the gap by stopping the feed rolls, but no trailing edge was ever seen at the input sensor.
200.16 Transport motor error detected
200.17 Took too long to ramp up transport motor
200.18 Manual feeder sensor never became uncovered from the sheet ahead.
200.19 The media never reached the input sensor, but was detected at manual feeder sensor. 
						

							Diagnostics information2-9
4512-630
200.20 The media is too long over the manual feeder sensor. Possible causes include multi-sheet feed, media size 
(length) problem, pre-staged media in the tray.
200.22 FAILED SMALL GAP OR NO GAP JAM RECOVERY. Engine detected small gap or no gap at the manual 
feeder sensor, opened the gap by stopping the feed rolls, but never saw the leading edge of the second page at 
the input sensor.
200.23 Laser Servo never started due to potential conflict with the transfer servo. Possible causes: slow or missing 
transport motor positional feedback, or the media is transferred too quickly to the input sensor.
200.24 The measured gap at the input sensor is too small to meet the video delivery requirements. (There is not 
enough time since prior image finished to start new image)
200.26 The trailing edge never cleared the input sensor when feeding out the media that was detected during warm-
up.
200.27 Printhead Driver: Mirror motor fell out of lock condition after the media at the input sensor - more time elapsed 
since the printhead than the expected stable lock time, but less than the printhead jitter-stable specification.
Mirror motor fell out of lock condition after media at the input sensor - more time elapsed since the printhead 
than expected stable lock time, but less than the printhead jitter-stable specification.
200.28 First writing line of a page at the developer nip, but laser servo cleanup is not complete. Likely pre staged 
media or a fast paper feed.
200.29 Printhead drive control out of range due to an external event beyond what the control is designed to handle. 
Probable causes: ESD or noise on hsync signal.
200.30 Narrow media sensor covered during warm-up.
200.32 Media more than 14 inches too long over the manual feeder sensor. Possible causes include multi-sheet feed 
or pre-staged media in the tray.
200.33 Page from tray 1 did not reach the input sensor after multiple attempts. Page did make it out of the tray at least 
as far as the manual feeder sensor. Possible cause is that the page stalled at the alignment gate.
200.34 Timed out waiting for page from tray 1 to reach the input sensor after multiple pick attempts, but the page was 
later detected at the input sensor while waiting for any page(s) ahead to clear the paper path. Possible cause is 
that the page is delayed at the alignment gate.
200.35 Failed to create hsync during auto alignment
200.36 Lost hsyncs during auto alignment
200.37 Timeout on data collection during auto alignment
200.38 Interpage servo gap is smaller than expected for printhead offset target evaluation
201.00 Paper jam between input and exit sensor
201.01 Transport motor identification failed to identify either motor after two tries.
201.02 Exit sensor never made by leading edge of page. Also known as internal jam.
201.03 Video never started on the page at the input sensor within two inches after hitting the input sensor
201.05 Restart attempted after an internal jam without the cover open/close event. It is likely that the jam was never 
cleared.
201.25 Exit sensor never made by leading edge of media when feeding out the media that was detected during warm-
up.
201.26 Page at fuser nip before fuser started ramping toward desired temperature. Indicates code may be receiving 
more hall interrupts than intended

Error Description 
						

							2-10Service Manual 4512-630
201.27 Page at fuser nip before fuser reached acceptable operating temperature. Page arrived at fuser earlier than 
expected, so it was probably staged
202.00 Paper jam around exit sensor.
202.01 Exit sensor never broke on the trailing edge of the sheet at the exit sensor.
202.02 Exit sensor never broke from sheet ahead of page heading toward the exit sensor.
202.06 Exit sensor bounced
202.13 Exit sensor covered, media not expected (media not in machine during warm-up)
202.25 Exit sensor never broke from the sheet ahead of the page heading toward the exit sensor when feeding out the 
media detected during warm-up.
202.26 Trailing edge never cleared exit sensor when feeding out media that was detected during warm-up.
202.32 Long media or shingled multi feed stopped before sending to duplex.
231.00 Duplex jam while reversing into the device
231.01 Duplex sensor never made by leading edge reversing into the duplex.
231.02 Bouncy duplex sensor never made.
232.00 Duplex jam while staging in the device
232.01 Duplex sensor never broke by the sheet ahead after reversing into the duplex.
232.02 Page in duplex ahead of current reversing page never staged.
233.00 Duplex jam while picking from the device
233.01 Page in duplex never picked.
233.02 Feed error picking from the duplex.
233.03 Paper never reached the input sensor, but was detected at the manual feed sensor.
234.01 Duplex sensor covered during warm-up.
235.01 Invalid duplex media
241.00 Paper jam near tray 1.
241.10 Second pick attempt failed from Tray 1
241.12 Second pick from manual feeder, tray 1, or feeder failed when the media was in the source while other sheets 
were committed to the paper path.
241.16 Failed to feed from tray 1. Pages in the paper path have been flushed to the output bin.
241.17 MISIDENTIFIED SMALL GAP JAM. Engine detected small gap at the manual feeder sensor, attempted to 
open the gap by stopping the feed rolls, trailing edge was seen at the input sensor, manual feeder sensor is no 
longer covered.
241.18 MISIDENTIFIED NO GAP JAM. Engine detected no gap at the manual feeder sensor, attempted to open the 
gap by stopping the feed rolls, trailing edge was seen at the input sensor, manual feeder sensor is no longer 
covered.
241.19 Second pick attempted failed from Tray 1, no pages printed since calling a 241.10 or a prior 241.19.
