Paper Jams and Head Crashes
PA09: True Paper Jams
The sound of crinkling paper usually precedes the notification of a paper jam, PA09.
Paper must be cleared to continue printing.
Cause
Causes include debris or objects in the paper path; platen out of position; bent or
curled media prior to entering the printer; repeated paper jams are often caused by small
pieces of paper that are left behind from a first sheet that ripped.
Solution
1. Open clamshell and remove jammed media from the paper path.
2. Check for small pieces of paper that may be caught in pinch rollers and other tight
places. These small pieces need to be removed before continuing printing.
PA10: False Paper Jams
An error message (for example, “Media present in paper path”) claims that there is a
paper jam but there is not. In this condition, the cap will be unable to cap the printhead.
The maintenance module is also be unable to wipe the printhead as the print engine is set
as though media is blocking its path.
Cause
Causes of false paper jams include faulty sensor wiring, or PCA, and debris blocking
sensor.
Solution
1. First, open the clamshell and check for any small pieces of debris that may be blocking
the entry or exit sensor causing this error.
2. If determined that no foreign object is blocking the sensor, use TCL commands or
scripts to determine if the sensor is functioning.
Query sensor state. (1 or 0)
Using a piece of media or some other object, block or cover the sensor and query again
to see is the state has changed. (1 or 0)
3. Check for voltage at sensor and leaving MPCA.
4. Check continuity of wiring from MPCA to sensor end of cable.
PA11: Wrinkled Paper
Paper does not come out flat but also does not jam: any folding, marking or ripping
on the output media.
Cause
Damaged or incompatible media; misadjusted feeder; object in paper path.
Solution
1. Adjust feeder so as not to cause damage to media.
2. Check to ensure that proper media is being used.
