Troubleshooting

Introduction

The main types of possible errors are the following.

Errors that relate to the machine
Errors that relate to the jobs
Toner problems that relate to the use of fiber-rich media.

This section gives an overview of the possible errors and the solutions to these errors.

NOTE

Only operators who received the special maintenance training are allowed to replace or clean parts and solve paper jams in the process units.

Overview of the possible machine errors

Table 1. Handle the machine errors
Error	Solution	Additional information
Paper jam	Follow the instructions on the control panel.	After you solved the error, the machine starts from the point where the printing stopped due to the error. Please check for double prints.
Software error	Follow the instructions on the control panel.	A message on the control panel will indicate that you must restart the machine.
Service required	Follow the instructions on the control panel.	A message on the control panel will indicate that you must call Service.
Maintenance required	Follow the instructions on the control panel.	The maintenance wizard appears. You need to have access rights to perform maintenance tasks. NOTE Only trained operators are allowed to perform maintenance tasks.
Unit reconditioning	Follow the instructions on the control panel.	After an error was solved, the machine checks if the print job can continue from the point where the printing stopped. When you use cyclic media, you must probably remove a couple of sheets.
The system cannot determine if the output is complete	Follow the instructions on the control panel and check the output.	The system can sometimes not determine if the output is complete. Then you must check the output. Touch the [OK] button when the output is complete.

Overview of Possible Job Errors

Table 2. Handle job errors
Error	Solution	Additional information
The required supplies are not available	Add the required supplies (media, toner and staples) before the machine stops printing.	The dashboard helps you to determine when the supplies are required.
The defined combination of job settings is not possible	The controller corrects the settings. You must define a correct combination of job settings in the [Edit] section of the [Jobs] view on the control panel.	The solution depends on the place where the job settings are defined. When the job settings are defined in an application or printer driver, the controller automatically corrects the settings. When you define the job settings on the control panel, the control panel displays a message that the defined combination is not possible. The [OK] button is disabled.

Overview of the possible toner pollution problems using media with high amounts of paper dust

When you use media with a high amount of paper dust, you can have problems with toner pollution of the prints right after the automatic black image cleaning procedure. Therefore it is advised to enable the [Paper quality test] (see Change the advanced media settings - Start the Paper quality test) each time when a new batch of media is used. This is to be sure that the correct [Paper quality] setting is still at the right level for this new batch.

Toner pollution problem	Solution
Toner pollution on the first sheets after the automatic black image cleaning procedure.	Change the [Paper quality] setting from [Normal] to [Low] (see Change the advanced media settings - Change the Paper quality). Use the [Paper quality test] to determine if this new setting is the right cleaning mode for this media. The sheets of the 5^th set must be totally toner free, also at the edges of the media size width. When these sheets still show toner pollution, you can set the [Paper quality] setting to [Lower] (see Change the advanced media settings - Change the Paper quality). Use the [Paper quality test] to verify that this new setting is the right cleaning mode for this media.
Toner pollution on the first sheets along the edge of the sheet (2-3 mm) after the automatic black image cleaning procedure.	Change the [Paper quality] setting from [Normal] to [Low] (see Change the advanced media settings - Change the Paper quality). Use the [Paper quality test] to determine if this new setting is the right cleaning mode for this media. The sheets of the 5^th set must be totally toner free, also at the edges of the media size width. When these sheets still show toner pollution, you can set the [Paper quality] setting to [Lower] (see Change the advanced media settings - Change the Paper quality). Use the [Paper quality test] to verify that this new setting is the right cleaning mode for this media. NOTE When the peripheral pollution mainly occurs at 1 side of the sheet, it is advised to rotate the media in the paper tray by 180 degrees.
A combination of the above pollutions.	Change the [Paper quality] setting from [Normal] to [Low] (see Change the advanced media settings - Change the Paper quality). Use the [Paper quality test] to determine if this new setting is the right cleaning mode for this media. The sheets of the 5^th set must be totally toner free, also at the edges of the media size width. When these sheets still show toner pollution, you can set the [Paper quality] setting to [Lower] (see Change the advanced media settings - Change the Paper quality). Use the [Paper quality test] to verify that this new setting is the right cleaning mode for this media.
Ghost images in mid and high toner coverage areas.	Change the [Paper quality] setting from [Normal] to [Low] (see Change the advanced media settings - Change the Paper quality). If the print quality is still not optimal with respect to mentioned ghost images, you can set the [Paper quality] setting to [Lower] (see Change the advanced media settings - Change the Paper quality).
