Tips on preventing jams 
You can avoid most paper jams by correctly loading paper and specialty media.
The following hints can help you avoid paper jams:
•Do not load wrinkled, creased, or damp paper.
•Never mix media types within a tray.
•Flex, fan, and straighten paper before you load it.
•Do not exceed the maximum stack height.
•Push all trays firmly into the printer after loading them.
•Make sure the guides in the trays are positioned snugly against the paper or specialty media.
•Do not remove paper trays while a job is printing. Wait for a Load Paper or Ready light sequence before you 
remove the tray.
•Before loading transparencies, fan the stack to prevent sheets from sticking together.
•Do not use envelopes that:
–Have excessive curl
–Are stuck together
–Are damaged in any way
–Contain windows, holes, perforations, cutouts, or embossing
–Have metal clasps, string ties, or metal folding bars
–Have postage stamps attached
–Have any exposed adhesive when the flap is in the sealed position Transmission rate 3 seconds per page

2.  Diagnostic information
Start
CAUTION: Unplug power from the MFP before connecting or disconnecting any cable, assembly, or 
electronic card. This is a precaution for personal safety and to prevent damage to the MFP. 
This chapter contains the codes and diagnostic tools to aid in providing corrective action for a malfunctioning 
MFP. To determine the corrective action to repair an MFP, look for the following information:
•If you do not complete POST, verify the sequence of events during the POST. See “Power–On Reset 
(POR) sequence” on page 2-1.
•If you have a description of a problem, but no error message, see “Symptom tables” on page 2-2.
•If you have an error indication, see one of the following:
–“Service error codes” on page 2-9
–“User attendance messages” on page 2-19
–“Paper jam messages” on page 2-18
Power–On Reset (POR) sequence
The following is an example of the events that occur during the POR sequence when the MFP is turned on.
1.The function and scan quality LEDs illuminate for one second and then flash three times. 
2.Loading is displayed on the operator panel.
3.CIS lamp illuminates. The scanner performs a calibration.
4.The main motor runs momentarily.
5.The scanner CIS returns to the home position.
6.Close Door will be posted if the cover is open.
7.Any cartridge errors, such as Defective Cartridge, are posted.
