Front-panel errors Table 11-2 Numerical error codes (continued) Error code Recommendation 48.1.4 Carriage beam error. Restart the printer. If the error persists, call your service representative (see HP Customer Care Centers on page 93). If no error is reported but there is still some problem with substrate advance, go to the front panel and select the Substrate Management icon, then Carriage beam position > Carriage system recovery. 48.1.5 Carriage beam error. Restart the printer. 50:01 The substrate-advance sensor cannot track the substrate, either because the sensor is dirty or faulty, or because the substrate type is incompatible with the sensor. Clean the substrateadvance sensor (see Clean the substrate-advance sensor on page 33). If the error persists, turn off the substrate-advance sensor for the current substrate type. If the error occurs with all substrates, call your service representative. See HP Customer Care Centers on page 93. 50:03, 50.1:10, 50.2:10 The substrate-advance sensor is not working. Restart the printer. If the error persists, call your service representative. See HP Customer Care Centers on page 93. You can print without the substrate-advance sensor, but print quality may be affected. 65.04 Restart the printer. 68 This warning message indicates that the printer's internal counters are not functioning correctly. You are recommended to restart the printer in the near future. 78.1:04 The substrate preset is damaged or missing. Import or create a new preset for the loaded substrate. See the User's guide. 78.2:01 78.3:01, 78.4:01 78.5:01, 78.6:01 78.7:01 81:01 81.02:01, 81.02:03 The substrate may have become detached from the rear spindle, or the core is slipping on the spindle. This could mean that you have reached the end of the roll, or the spindle is not correctly inflated, or the dual-roll differential hub is locked. The substrate will be unloaded. Substrate may be detached from the rear spindle or slippage detected after forward movement, or the substrate has finished on the input spindle. Check that the input spindle is correctly inflated. Substrate may be detached from the front spindle or slippage detected after forward movement. Check that the input spindle is correctly inflated. This is displayed when printing double-sided, and trying to print side B, the printer cannot detect the Image Registration Line and the job will not be printed: 1. Recheck the position of the substrate, ensure the last Image Registration Line is aligned with the beginning of the platen. 2. Clean the Substrate Advance Sensor, refer to the Maintenance & Troubleshooting Guide for details of the procedure. There is a possible substrate jam, see The substrate has jammed on page 49. If you check the printer and see there is no actual jam, restart the printer. The tension roller in the Roll to Free Fall System has been raised while printing. As the Printer is unable to control the substrate tension the system cannot operate any longer. The system error is severe and a restart of the printer will be required. Check the Tension Roller Lever is closed. ENWW 91

Error code

Recommendation

48.1.4

Carriage beam error. Restart the printer. If the error persists, call your service representative

(see

HP Customer Care Centers

on page

). If no error is reported but there is still some

problem with substrate advance, go to the front panel and select the Substrate Management

icon, then

Carriage beam position

Carriage system recovery

48.1.5

Carriage beam error. Restart the printer.

50:01

The substrate-advance sensor cannot track the substrate, either because the sensor is dirty or

faulty, or because the substrate type is incompatible with the sensor. Clean the substrate-

advance sensor (see

Clean the substrate-advance sensor

on page

). If the error persists, turn

off the substrate-advance sensor for the current substrate type. If the error occurs with all

substrates, call your service representative. See

HP Customer Care Centers

on page

50:03, 50.1:10, 50.2:10

The substrate-advance sensor is not working. Restart the printer. If the error persists, call your

service representative. See

HP Customer Care Centers

on page

. You can print without

the substrate-advance sensor, but print quality may be affected.

65.04

Restart the printer.

This warning message indicates that the printer's internal counters are not functioning

correctly. You are recommended to restart the printer in the near future.

78.1:04

The substrate preset is damaged or missing. Import or create a new preset for the loaded

substrate. See the

User's guide

78.2:01

The substrate may have become detached from the rear spindle, or the core is slipping on the

spindle. This could mean that you have reached the end of the roll, or the spindle is not

correctly inflated, or the dual-roll differential hub is locked. The substrate will be unloaded.

78.3:01, 78.4:01

Substrate may be detached from the rear spindle or slippage detected after forward

movement, or the substrate has finished on the input spindle. Check that the input spindle is

correctly inflated.

78.5:01, 78.6:01

Substrate may be detached from the front spindle or slippage detected after forward

movement. Check that the input spindle is correctly inflated.

78.7:01

This is displayed when printing double-sided, and trying to print side B, the printer cannot

detect the Image Registration Line and the job will

not

be printed:

Recheck the position of the substrate, ensure the last Image Registration Line is aligned

with the beginning of the platen.

Clean the Substrate Advance Sensor, refer to the

Maintenance & Troubleshooting Guide

for details of the procedure.

81:01

There is a possible substrate jam, see

The substrate has jammed

on page

. If you check the

printer and see there is no actual jam, restart the printer.

81.02:01, 81.02:03

The tension roller in the Roll to Free Fall System has been raised while printing. As the Printer is

unable to control the substrate tension the system cannot operate any longer. The system error

is severe and a restart of the printer will be required. Check the Tension Roller Lever is closed.
