Hex Code 24
Paper-pass error – upper
tray.
If media didn't reach the paper-pass sensor 1, check to see if
media was picked from the tray.
Clean the paper-pick rollers in the print engine. Refer to
Chapter 7 topic “Cleaning.”
Ensure
that
the alignment roller pressure springs at each end
of the aligning rollers hold the rollers firmly together.
Ensure that the paper-feed motor and gear train operate
correctly.
Ensure that the paper path is clear.
If media reached the paper-pass sensor, ensure that
paper-pass sensor 1 operates properly. Refer to the topic
“Switch and interrupt sensor checks” on page 9-12.
Ensure that
the lower tray assembly is correctly installed and
its door is closed if the printer is picking from the lower tray.

Hex Code 25
Paper-pass sensor 2
error.
Clean the aligning rollers. Refer to Chapter 7 topic
“Cleaning”.
Ensure that
the alignment roller pressure springs at each end
of the aligning rollers hold the rollers firmly together.
Ensure that the paper path is clear.
If media reached the paper-pass sensor, ensure that the
paper-pass sensor 2 operates properly. Refer to the topic
“Switch and interrupt sensor checks” on page 9-12.
Check the aligning roller clutch and solenoid for proper action.

Hex Code 26 Clamp
error.
Check to see that the paper clamp is opening properly when
the drum is rotated backward into the drum stops. Determine
if the drum rotates smoothly to the clamp-open position.
Ensure that the clamp holds media firmly; if not, clean it.
Ensure that no foreign matter interrupts the paper clamp
sensor.
Ensure that the bail rollers operate smoothly and correctly.
Ensure that the paper clamp sensor operates properly.

Hex Code 27 Media size
error.
Ensure that the proper media is loaded in the tray being used.
The tray “informs” the print engine of the paper that should be
loaded in the tray. The actual paper size is not sensed by the
print engine.
Ensure that paper-pass sensors 1 and 2 are operational and
properly adjusted. Refer to the topic “Switch and interrupt
sensor checks” on page 9-12.
