WARMING UP" (continuous) Message
During normal operation, the printer displays a 00 READY message within 90 seconds of power-on.
If the 02 WARMING U P message persists for longer than 90 seconds, check the following
Table 7-4.02 WARMING UP (continuous) Checks
1. Are there host system interface problems?
Disconnect the interface wble from the printer,
power printer OFF, then ON, May be caused
by a parallel cable connected to a serial port
or vice-vers% both serial and parallel.cables
attached, or a bad host interface.
2.
Is J209 fiumper) instiled on the DC Instil jumper.
Controller?
13.
Is the Control Panel mble fully connected? lReseat/replace the Control Panel cable.
14.
Is the Control Panel Assembly inoperative? lReplace the Control Panel Assembly.
15.
Is the Interface/Formatter PCA inoperative? \Replace the Interface/Formatter PCA.
"11 PAPER OUT" Message
"PC/EC LOAD" Message
Two conditions result in the 11 PAPER OUT (HP 33440) or PC LOAD [paper size]/EC LOAD
[envelope size] (HP 33449) messages; first, the absence of the input tray and, second, the absence
of media in the tray. The tray is sensed as the tray identifier tibs contact one or more of the three
tray identifier microtitches in the tray input mvity of the printer. Under normal conditions, the
PC/EC LOADmessage is dso generated when a paper or envelope size other than what is loaded in
the printer is died for by the user or sotiare.
The Paper Sensing Arm is lomted in the paper input area of the printer. During normal operation,
the Paper Sensing Arm flag rests on the media instiled in the paper tray. The Sensing Arm flag
is attached to a shti. The opposite end of the shfi is a photointerrupter that rotates through the
PS301 (paper out) and PS302 (manual feed) sensors on the Paper Control PCA.
When the tray is empty, the Paper Sensing Arm flag swings through an opening in the base plate
of the tray, allowing the photointerrupter to rotate and block sensor PS301.
The same Paper Sensing Arm is also used for manual feed operation. When media is inserted in
the manual feed slot atop the input tray cover, the photointerrupter rotites toward the rear of the
printer and blocks sensor PS302 on the Paper Control PCA. This indicates to the DC Controller
PCA that media is in position for manual feed.

The following checks are applicable to both "false paper out" or "undetected paper
,P8
out" conditions. The undetected paper out condition will normally result in a 13
w
PAPERJAMerror with no paper in the input tray.
