System Error: 71:03
Problem Description: Out of memory
Corrective action: Restart the product.

Warning: 71:04
Problem Description: Out of memory.
The total memory available in the product depends on its configuration. It is reported as HP-GL/2 memory or PS/PDF memory. If the amount of memory that the product needs to process the file is more than the amount available, the product will display this system warning. The amount of memory required for processing the file is known as the ‘display list memory’:
● The display list memory should not be confused with the file size of the print job. The size of the display list memory depends on several variables such as the resolution, file size and file content.
● The display list memory is not visible to the user, but can be consulted by engineers to troubleshoot out-of-memory issues.
● There have been a few cases in which a print job with a relatively small ƭle size has triggered an
out-of-memory message. Such print jobs typically have a large number of objects in them or
have complex objects such as raster images with gradients or objects with multiple layers.
Corrective action: Try the following:
1. Upgrade the ƭrmware to the latest version available.
2. Decrease the print resolution to 300 dpi.
NOTE: If the customer does not accept the print quality after reducing the resolution or using
Econofast print mode, proceed to the workaround in step 3.
– The resolution required by the product to process the ƭle is set by the print mode selected
(Best, Normal, Fast). There is a setting available that enables you to decrease the resolution
for each print mode to 300 dpi. If this setting is used, the rendering resolution will be
reduced, but the output (printing) resolution will remain the default of the selected print
mode. There could be an impact on Image Quality because of the reduction in the rendering
resolution; this will be especially noticeable in circles and lines with very low inclination.

3. Use the ‘Econofast’ print mode. The rendering resolution will be set by default to 300 dpi. In the
Paper/Quality tab of the product properties window, select Custom options and press the
Settings button. In the Custom Print Quality Options window, check the Economode box.
NOTE: If the Out of Memory message still persists, proceed to the next workaround.
4. Out of Memory issues can always be solved if the processing of the job can be performed before
reaching the product. This can be done by selecting ‘Send Job as Bitmap’. The main processing of
the print job will then be performed by the computer. This form of printing is recommended when
the print job contains raster images, and mixed plots with raster images and lines, because the
process of turning a print job made of raster images to vector images leads to a signiƭcant
increase in the display list memory.

System Error: 81:01
Problem Description: Paper axis error—the copier will restart and run a diagnostic test
Corrective action: None

System Error: 81:YZ
Initial checks: This error can occur because the product has been dropped during transportation, causing structural damage. Before continuing with the 81:YZ troubleshooting, first look for structural damage.
To identify the structural damage, look for the following three things:

● Consistent 81:YZ error codes.
● Platen fingers rubbing on the roller surface, leaving black marks on the roller.
● A gap on the platen beam. If there’s any gap in Z (vertical direction) between the plastic feature of the platen and the metal side plate, then the chassis is damaged and the unit cannot be repaired.

Problem Description:
Problem with paper advance. This source of error could come from an error in any of the following systems: paper motor, disk encoder, cables or main electronics.
Corrective action:
Try the following:
1. Check for any visible obstacles restricting the movement of the Drive Roller. If there is a wrinkled mass of paper inside the paper path, lift the Pinchwheels (using the Media Lever) and clear the obstruction.
2. Perform the Media Drive diagnostic test to troubleshoot the problem further. 
3. Perform the Rewinder diagnostic test to troubleshoot the problem further. 
4. Check the connections on the Engine PCA; the Media Advance Drive is connected to the connector labeled Paper Motor.
5. Adjust the encoder disc and motor mount configuration using the Media Advance Drive installation instructions.
6. Replace the Media Advance Drive. 

System Error: 86:01 (or 86:11)

How to troubleshoot SE 79:04

The system error 79:04 is a generic error (equivalent to a blue screen in windows). It’s the system error that the product will display when an unknown exception occurs that cannot be identified as relating to any specific subsystem of the product.

Since this is a generic error, there can be multiple causes behind it. This document will cover the most probable causes behind a system error 79:04 and will recommend the most efficient troubleshooting steps to resolve customer issues.

It is important to mention that, although 79:04 system errors can be caused by a hardware malfunction, the vast majority of 79:04 system errors are pure software or firmware issues. Before doing anything else, you are recommended to try the following general-purpose solutions.

1. Update the product’s firmware to the very latest available firmware version, even if the product appears to be running the latest firmware already.
2. Restore the factory settings from the Touch Screen Panel's Setup menu.
If these do not solve the problem, continue reading about other possible solutions below.

Possible causes
Since the 79:04 system error is a generic error, the number of possible causes behind it is large. The majority can be grouped, however, into the following groups.

Job-related SE79:04
A specific print job that is not correctly formatted for the product or that is not correctly processed by it can trigger a 79:04 system error.
The incorrect format or processing can come from two sources:
● Incorrect commands in the job itself. For example, a PS job with some commands that do not have the correct PS format.
● Issues applying to the settings in the job
Possible symptoms

79:04 caused by a print job always have the same symptoms:
1. The job is received by the product and starts to process.
2. In the middle of the processing, the product stops and displays 79:04.
3. The product will display the 79:04 system error again after reboot. This is due to the fact that the product will try to reprint the job, which is pending in the queue, after reboot.
4. After the second reboot, the product will start up normally
5. If the same job is sent again, it will always produce a 79:04 system error
These types of 79:04 system errors are normally caused by jobs that have been generated by 3rd party applications (RIPs, 3rd party drivers, files exported by an application to PS, PDF, HP-GL/2, RTL, … or any other format supported by the product). Jobs generated by HP drivers will not normally generate 79:04
