Troubleshooting Jams; Jams; Clearing Jams - HP Color LaserJet 9500 Service Manual

Troubleshooting jams

Jams occur when media either does not reach or does not clear a sensor along the paper path in
a specific amount of time. If a jam occurs, a JAM IN LEFT ACCESSORY message appears on the
printer or MFP control panel.
Error codes in the event log indicate locations of jams. Print and evaluate an event log to
determine the exact location of a jam.

Jams

Jams can occur when the following conditions exist:
Send a print job from the problem source(s) to the problem destination(s). Try to recreate the jam
errors by performing a paper-path test.
When evaluating print jobs, make sure that all of the appropriate settings are selected. Keep in
mind that application settings take priority over driver settings, which take priority over the printer
or MFP control-panel settings. If a single setting is not present in the application, but is set in the
driver, that setting overrides the control-panel settings.

Clearing jams

Note Open and close all output device covers to clear the jam message. After removing a sheet, you
might need to check other areas for the presence of other sheet.
All portions of a jammed piece of media must be removed, or you might experience repeated

jams.

If the jam persists, try the following:

The print media does not meet the specifications listed in the HP LaserJet Printer Family
Print Media Guide.
The media is in poor condition.
Sheets are pulled from the face-down bin or the face-up bin before the print job is complete.
If PostScript® is installed, use the JAM RECOVERY=ON menu item under the PostScript Menu.
The output device will attempt to automatically recover from jams.
Initiate a form feed from the computer or from the printer or MFP control panel. A form feed
might flush out any paper or envelopes that remain in the output device.
Check to make sure you have located and removed all scraps of media from inside the
output device.
Do not use previously printed media or torn, worn, or irregular media.
Check the media specifications. If it is outside of the recommended specifications, problems
might occur. See the HP LaserJet Printer Family Print Media Guide.
Clean the output device.
