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
