Troubleshooting postscript (PS) errors

The following situations are PS language specific and might occur when several printer languages are being used.

NOTE

To receive a printed or screen displayed message when PS errors occur, open the Print

Solution

The job prints in Courier (the printer's default typeface) instead of the typeface you requested.

A legal page prints with clipped margins.

A PS error page prints.

Limit Check Error

VM Error

Range Check

The requested typeface is not downloaded. A personality switch might have been performed to print a PCL job just before the PS printing job was received.

Print job too complex.

Print job might not be PS.

Print job is too complex.

Font Error

Font Error

Download the desired font and send the print job again. Verify the type and location of the font. Download to printer if applicable. Check with the software documentation.

You might need to print your job at 600 dots per inch, reduce the complexity of the page, or install more memory.

Make sure the print job is a PS job. Check to see whether the software application expected a setup or PS header file to be sent to the printer.

Print cartridge problems

Checking the print cartridge

Image formation defects are frequently the result of problems in the print cartridge. If there is any doubt, always replace the print cartridge before troubleshooting image defects.

Use the following checklist to make sure that the print cartridge is still operable.

Make sure that the print cartridge is installed properly and the shipping tape is removed.

Inspect the print cartridge for toner level.

Check the expiration date stamped on the print cartridge box.

Check the print cartridge to see if it has been disassembled or refilled.

Inspect the print cartridge to see if toner is leaking through worn seals.

Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or scratched. Touching the drum contaminates the photosensitive surface and can cause spotting and image defects.

Blurred areas on printed pages indicate that the photosensitive drum in the cartridge has been overexposed to light. Because overexposure to light causes permanent damage to the photosensitive drum, the cartridge should be replaced.

NOTE

A standard-capacityprint cartridge weighs approximately 765 grams (1.69 lb) when full and

 

approximately 675 grams (1.49 lb) when empty. An extra-capacityprint cartridge weighs

 

approximately 986 grams (2.17 lb) when full and approximately 766 grams (1.69 lb) when

 

empty. These values are subject to change without notice.

To redistribute toner in the print cartridge

Before installing a new print cartridge or when toner begins to run low, redistribute the toner by rotating the cartridge back and forth five or six times.

Solving image-qualityproblems

Use the following tables to help solve problems with printed pages.

If the problem occurs when printing, see Table 7-8. Solving print image-quality problems. Also, see Table 7-2. Solving print paper-feed problems.

The printed page has a gray background.

Cause

The print density setting is too high.

The media basis weight is too high.

The humidity level is too low.

The print cartridge is worn or damaged.

Toner smears appear on the printed page.

Cause

If the toner smears appear on the leading edge of the media, the media guides are dirty.

The media you are using does not meet HP's specifications (for example, it is too moist or too rough).

The print cartridge is worn or damaged. The pressure roller in the fuser is damaged.

The fuser temperature is too low.

Solution

Decrease the amount of background shading through the device configuration utility.

Change the media to a lower basis weight.

Very low humidity can increase the amount of background shading. Move the printer to a different location, or decrease the background shading through the device configuration utility.

Replace the print cartridge.

Solution

Wipe the media guides with a dry, lint-freecloth.

Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Media Guide.

Repetitive vertical defects appear on the printed page.

Cause

Solution

If the repetitive mark occurs at equal distance between marks, either the print cartridge or a printer roller is damaged.

The internal parts have toner on them.

Use the repetitive image defects table to identify the spacing (Repetitive image defects). Check the appropriate component and replace it if necessary.

If the defects occur on the back of the page, the problem will probably correct itself after a few more printed pages. Otherwise, clean the printer. (See Cleaning the printer.)
