Running User Diagnostics

You may be prompted by the Xerox Nuvera, or by a Customer Support representative to access and run diagnostic routines. The diagnostic routines are useful for getting the system back into proper calibration or adjustment, and/or as a part of general system maintenance.

To access User Diagnostics

1. On the Xerox Nuvera user interface, select [System: User Diagnostics]. The User Diagnostics window appears. Depending on your system configuration, available diagnostic routines are listed
2. After checking with your authorized Xerox representative, select one of the routines to begin a diagnostic routine or to enable/disable a routine or algorithm.
3. Follow the on-screen instructions to complete the chosen diagnostic routine.

Depending on your system configuration, available diagnostic routines may include any or all of the following.

 

System

Perform the following routines as needed for the Xerox Nuvera systems. Enable or disable the following optimization switches:

System Optimization Customer Setup

• Heavy-Weight Stock Jobs - Enhance Image Permanence (EIP) - To select, you must first uncheck AIP. Select EIP if printing media with challenging fix characteristics, such as heavy rough stock and some coated stock. Selecting EIP runs the fuser at a constant, higher temperature. This higher temperature may cause curl in lightweight stocks and degrade output stack quality.
• Automatic Image Permanence for All Stock Weights (AIP) - AIP is the preferred mode. Use this routine to adjust the fuser temperature accordingly based on the programmed job information.

NOTE: Automatic Image Permanence (AIP) is dependent on how the user programs media characteristics into the stock library or into each feed tray. The system sets the temperature based on the heaviest-weight stock in the job. Excessive curl can result if light-weight stock is used with heavy-weight tabs or inserts. Spending a few moments to correctly program the media is important to getting the optimal performance from your Xerox Nuvera system. The Xerox Nuvera runs in Nominal Mode if neither EIP or AIP is selected. Nominal Mode runs at a mid-level fusing temperature that is satisfactory for most media.

• Light-Weight Stock Jobs - Optimize Image Quality - use to improve image quality problems on lightweight stock resulting from deletions on large format media with low area coverage. These deletions are typically only seen on side 2 of 2-sided jobs. Do not use with heavyweight stock and use only when directed to do so by a Xerox representative. Do not select this feature and EIP mode at the same time.
• 2-sided Jobs - Reduce Up-Curl - enable when there is excessive upcurl in the output stacks. The system prints side 2 first and then side 1 to avoid the sheet being inverted after the second image. This causes the output to have down curl instead of up curl. Note that this selection does not apply to jobs programmed with ordered stock and 3-hole punch stock. If used, the system ignores the Reduce Up-Curl feature and prints side 1first.
• Cycle Up Purge Enabled - not available to the user. This feature is used only by a Xerox technical representative.
• Feed Until Empty Algorithm - when enabled, the system empties stock from the secondary feed tray in use before switching back to the primary tray.
• Crash Recovery: Last Sheet Delivered Not Known - If the system crashes while printing a large job and you need to restart DocuSP and reboot the system, the system will attempt to perform a job recovery. If the system knows the last sheet delivered to the finisher, the settings for this feature are not required and the job is recovered automatically. However, in case the system crash affects the finisher's ability to correctly detect the last sheet and automatically perform job recovery, use this feature to select either [Use Best Guess](default) or [Do Not Recover Job] from this drop down menu to indicate the type of job recovery to use. Select [Use Best Guess] if the last sheet delivered is not known and you want the system to still attempt to recover the job. The system displays messages to check the output for duplicate pages or missing sheets. Select [Do Not Recover Job] if you want to recover the job, perform paper clearance and resubmit the job manually. The job remains unrecoverable in the inactive queue. This feature is not used when the system is only experiencing jam recovery or jam faults.
• Recovery Offset Enabled - If selected, on systems equipped with either an MFF or BFM only, the first recovered sheet delivered to the finisher following a jam will be offset from the rest of the unfinished set (this applies to unfinished sets only and not stapled sets). It is intended to help the operator examine the set for completeness following a jam. Only the first sheet after recovery is offset.
  
• Advanced User Diagnostics - If the Xerox Productivity Plus (XPP) service option is enabled, this diagnostic mode is intended for and accessed by a trained customer operator only. The trained operator logs onto and accesses these advanced diagnostics to perform certain repair and maintenance procedures without the need to contact Service. For more information, refer to your XPP documentation or contact a Xerox sales representative.

MFF

• dc1255 Booklet Staple Position Setup - use to align the staples on a folded booklet
• dc1254 Booklet Crease Position Setup - use to align the folded edge on a folded booklet

Document Scanner

• Document Glass Scanner Setup - use to establish the position of the Document Glass top and left registration edges, and set the scan speed of the Document Scanner

 

Print Engine

• dC0604 PE Registration Setup - use to set image registration, magnification, and skew. Also, use to align and register the image on side 2 with the image on side 1
• dC0943 Corotron Cleaning Routine - use weekly to remove dust and dirt that has built up on the corotron
• Image Quality Setup - use if experiencing image quality problems after running the Corotron Cleaning routine
