NOTE: If the 4635/180 IPS does not continue printing after a paper tray fault or after paper is loaded, lower then raise the tray. The system should resume printing. Frequent misfeeds Frequent misfeeds may be caused by a glazed feed belt. A glazed belt is the most common cause of one tray misfeeding more than another tray when the same kind of paper is used.
Clearing paper misfeeds and jams 2. Lightly moisten a lint-free towel with film remover and thoroughly wipe the outside surface of the feed belt in the same direction as the ribs on the belt. (Wiping from side to side might pull the belt off its track.) Allow a few seconds for the film remover to evaporate. 3. Latch the paper feeder assembly by pressing down on the bright green dot. Slide the paper tray completely back into the printer Operate the system as usual.
Clearing paper misfeeds and jams Clearing paper jams Paper sometimes jams as it leaves the feeder trays or moves through the paper path. You must clear the paper jam before you can continue to print. The two illustrations below show the areas along the paper path in which jams may occur. Figure 4-1. Areas along the simplex paper path Figure 4-2.
Clearing paper misfeeds and jams Jam display on printer console In the event of a jam, the printer console displays the following information: • The message display describes the areas of the printer you must check and clear. • The graphic display shows the location of the jams and the doors you open to access them. 1 2 Figure 4-3.

5. Optimizing print quality This chapter discusses methods of checking and improving print quality. NOTE: One way to test print quality is to print a sample document. For information on printing sample documents, refer to The Guide to Configuring and Managing the System. Product features that affect PostScript print quality You can improve the appearance of your documents by being aware of potential problems created through the use of proprietary PostScript extensions and device-dependent operators.
Optimizing print quality Device-dependent operators Some PostScript operators result in device-dependent PostScript files. “Device dependence” means that devices having different output characteristics may produce different-looking output even though they use the same software. This section documents the most serious examples of device dependence. The PostScript Language Reference Manual, second edition, lists all of the graphics state operators that are considered device-dependent.
Optimizing print quality Gray shading—settransfer and transfer function The PostScript operators settransfer and setcolortransfer are used to change the procedure for mapping perceived color values in the output of the print device into specified color values in the PostScript master. PostScript devices use an internal transfer array or procedure that takes into account the printing characteristics of their marking engines in order to produce levels of color.
Optimizing print quality Smooth curves—setflat PostScript masters that use the PostScript operator setflat produce inconsistent output across different PostScript printers. setflat controls curve rendering smoothness. PostScript curve operators use cubic Bezier control points to define the curve shape. These curves can be rendered from straight line segments. Normally the line segments are so short that the curve appears smooth.
6. Resolving printer problems This chapter describes printer-related problems other than paper jams, and suggests corrective actions. (Refer to “Clearing paper misfeeds and jams” for information on paper jams. Symptom Probable cause Action Printed sets are not stitched. Stitcher/stacker is out of wire (fault code L152), or is jammed (fault code L172), or stitching head has malfunctioned (various fault codes).
Resolving printer problems Symptom Probable cause Action Paper does not stack evenly in the dual stacker trays. Scuffer arm weights are out of adjustment. If printer has adjustable weights under the scuffer arms, slide them to the right or the left. (Refer to “Clearing paper misfeeds and jams” chapter in this guide.) If the weights are bolted in place, ask your service representative to adjust them.
7. Resolving system problems This chapter describes various system problems and suggests corrective actions. NOTE: The syntax for the actions listed is for CLI users. If using the GUI, refer to the online help for equivalent procedures. Symptom Probable cause Blank display: pressing a key fails to restore image. Monitor is powered off; brightness and contrast controls are misadjusted; or there’s a more serious problem.
Resolving system problems Symptom Probable cause Action No jobs appear to be printing. Queueing or printing may be stopped. • Enter Show Status. • Enter Start Queueing or Printing. Scheduling policy may be First Come First Served (FCFS) and the next job may be ineligible. • Enter Show Scheduling Policy to determine current setting. • If scheduling policy is FCFS and the next job is ineligible, no jobs will print.
Resolving system problems Symptom Probable cause Action Job prints on the wrong paper, or is otherwise not as expected. Paper in the tray and tray settings do not match. • Check the trays and Enter Show Status. • Change paper in the tray or set the correct paper type using Set Tray. Job has a job ticket and specified virtual printer has SkipJTPreScan set to True. (Does not apply to IPDS.) • Enter List Virtual Printers. • Send to another virtual printer with SkipJTPreScan set to False.
Resolving system problems Symptom Probable cause The IPDS host receives a Not Ready message from the DocuPrint NPS/IPS. If a virtual printer is specified for a job, and the virtual printer properties are changed, then the virtual printer stops and sends a not ready message to the host. Action 1. Enter Show Status to ensure there is no other problem. If you have a stoppage due to the status shown, correct the problem status. 2.
