Using the Pass Through Mode Feature
The Pass Through Mode (PTM) is only available on the Xerox Nuvera 288 Digital Perfecting System, which is uniquely configured with two print engines instead of one.
The PTM feature is used to maximize print productivity in the event that only one of the print engines is up and running. If a print engine is shut down due to a fault, image quality mismatching, or pending maintenance, the PTM feature allows you to identify the print engine to use for continued printing of simplex or duplex jobs. The other print engine will only be used to pass paper through the system.
 |
NOTE: When printing with one print engine, the productivity rate changes from 288 ipm to 144 ipm. To always make full use of the system's productivity, make sure to disable this feature once the idle print engine is serviced and available for use. |
When to enable Pass Through Mode
The following are the circumstances under which you would enable this feature and print with only one print engine:
- One of the print engines is out of toner
- Required maintenance on one of the print engines is awaiting service (for example, the photo receptor belt needs to be replaced)
- Certain print engine faults or system faults
- The image quality between the two print engines does not match and you want to use the print engine that produces consistent image quality
If you encounter the following circumstances, contact Service. Do not use or enable this feature if the system is experiencing:
- Reoccurring jams
- Critical print engine problems
- Certain print engine faults
- Registration faults
|
NOTE: If PTM is enabled but a critical print engine problem or fault exists, the available print engine will not print. Since the same paper path is used whether PTM is enabled or disabled, the system is preventing any damage to the down print engine. |
To enable and use the Pass Through Mode
- From the DocuSP user interface, select the System menu.
- From the drop down menu, select [User Diagnostics: System Optimization Customer Setup]. The System Customer Setup dialog displays.
- From the Pass Through Mode drop down menu, select [Print with Engine A1 Only] to select only print engine A1 for printing or [Print with Engine A2 Only] to identify print engine A2 to use for printing.
- Close the dialog. The Pass Through Mode is in effect.
To disable the Pass Through Mode
Once the idle print engine is serviced, access and disable the PTM feature:
- From the DocuSP user interface, select the System menu.
- From the drop down menu, select [User Diagnostics: System Optimization Customer Setup]. The System Customer Setup dialog displays.
- From the Pass Through Mode drop down menu, select [Off] to instruct the system to use both print engines for printing.
- Close the dialog. The Pass Through Mode is disabled.
