Resolving paper-handling problems

The following table lists and explains common paper-handling problems.
Problem
Solution
Paper jam
  • See the user guide for instructions about clearing jams from the printer.

  • Make sure that the paper guides are adjusted properly. Slide the guides against the sides of the stack in the main input tray or the priority input tray to center the page. Make sure that the guides are not adjusted too tightly.
  • The media input tray might be too full. Remove some of the sheets.
  • Make sure that the media being used meets specifications. Click here to go to "Printer media specifications" for more information .

  • Make sure that the media being used is not wrinkled, folded, or damaged.
  • Make sure that the printer is clean. See the user guide for instructions about cleaning the printer.

  • If printing to the straight-through output path, close and open the door again to make sure that the green release levers are closed.
  • The paper might not have been removed from the main input tray before the tray was refilled. Always remove paper from the main input tray before refilling it.
  • Output capacity might have been exceeded in the paper output bin. Do not allow more than 125 sheets of 20-lb (75 g/m 2 ) bond weight paper to fill the paper output bin (less for heavier paper).

  • The pickup roller or printer separation pad might be dirty or damaged. Clean or replace the part. (See the user guide for information about cleaning and replacing the pickup roller and printer separation pad.)

Print is skewed (crooked)
  • Make sure that the media is loaded correctly. Be sure to center the paper with the side media guides. Verify that the guides are not adjusted too lightly or too loosely against the paper. Check for broken or missing guides and replace as necessary.
  • The input bin might be too full.
  • The paper weight or surface finish does not meet HP specifications. Check the media type and quality. Click here to go to "Printer media specifications" for more information .

More than one sheet of media feeds through the printer at one time.
  • The media input tray might be too full.
  • Make sure that the media being used is not wrinkled, folded, or damaged.
  • The paper might have been poorly cut by the manufacturer and is sticking together. "Break" the ream of paper by curving it into an upside-down u-shape. This can effectively decrease multifeeds. Also try turning the paper around to feed the opposite end first, or use a different type of paper.
  • The printer separation pad might be worn. See the user guide for information about changing the printer separation pad.

Printer does not pull media from the media input tray.
Printer curled the media.
Paper curl is inherent in the laser printing processes, and occurs when paper is subjected to heat. Paper curl tends to relax as the paper cools while resting on a flat surface.
  • Check the media type and quality. Both high temperature and humidity cause media to curl. Click here to go "Printer media specifications" for more information .

  • The media might have been in the input tray too long. Turn over the stack of media in the tray. Also, try rotating the media to 180 degrees in the input tray.
  • Open the straight-through output door to print straight through. See the user guide for information about media paths.

  • The fuser temperature might be too high. In the printer driver, make sure that the appropriate media type is selected. If the problem persists, select a media type that uses a lower fuser temperature, such as transparencies or light media.
  • Paper might not have been stored properly. Whenever possible, store paper in its sealed ream at room temperature.
  • The media might be too long for the printer output bin. Use the long media extension.
The printed media does not exit to the correct path.
Open or close the straight-through output door to reflect the desired output path. See the user guide for information about media paths.
Print job is extremely slow.
The maximum speed of the printer is up to 18 pages per minute for the HP LaserJet 1150 printer and up to 20 pages per minute for the HP LaserJet 1300 series printer. The print job might be very complex. Try the following:
  • Reduce the complexity of the document (for example, reduce the number of multiple graphics).
  • In the printer driver, set the media type to plain paper. (This might cause toner to fuse improperly if heavy media is being used.)
  • Add printer memory. See the user guide for information about installing dual inline memory modules (DIMMs)(HP LaserJet 1300 series only)

  • Narrow media or heavy media will slow printing. Use normal media.

Printed page is different than what appeared on screen

The following table lists and explains common problems.
Problem
Solution
Garbled, incorrect, or incomplete text
The parallel or universal serial bus (USB) cable might be loose or defective. Try the following:
  • Disconnect the cable and reconnect it at both ends.
  • Try printing a job that is known to work.
  • If possible, attach the cable and printer to another computer, and try printing a job that is known to work.
  • Try using a new IEEE-1284 compliant parallel or USB cable.
The wrong printer driver might have been selected when the software was installed. Make sure that the HP LaserJet 1150 or HP LaserJet 1300 is selected in the printer properties.
There might be a problem with the software program. Try printing from another software program.
Missing graphics or text, or blank pages
  • Make sure that the file does not contain blank pages.
  • The sealing tape might still be in the print cartridge. Remove the print cartridge, and pull out the sealing tape.
  • Reinstall the print cartridge. See the user guide for information about removing print cartridges. To check the printer, print a demo page by pressing the GO button.

  • The graphic settings in the printer properties might not be correct for the type of job being printed. Try a different graphic setting in the printer properties. See the user guide for information about changing printer properties.

  • The printer driver might not work for the type of job that is being printed. Try using a different printer driver (software), such as the printer driver for the HP LaserJet III.
NOTE: If a different printer driver is used, some product features might not be available.
Page format is different than on another printer
If an older or different printer driver (printer software) was used to create the document or the printer properties settings in the software are different, the page format might change when the new printer driver or settings are used to print. To help eliminate this problem try the following:
  • Create documents and print them using the same printer driver (printer software) and printer property settings regardless of which HP LaserJet printer is being used to print them.
  • Change the resolution, paper size, font settings, and other settings. See the user guide for information about changing printer properties.

Graphics quality
The graphics settings might be unsuitable for the print job. Try the following:
  • Check the graphic settings, such as resolution, in the printer properties and adjust them as necessary. See the user guide for information about changing printer properties.

  • Try using a different printer driver (software), such as the printer driver for the HP LaserJet III.
NOTE: If a different printer driver is used, some product features might not be available.

Printer media specifications

Choosing paper and other media

HP LaserJet printers produce excellent print quality. It is possible to print on a variety of media such as cut-sheet paper (including up to 100% recycled fiber content paper), envelopes, labels, transparencies, vellum, and custom-sized paper.

The printer can use a variety of paper and other print media in accordance with the guidelines in this document. Media that does not meet these guidelines might cause the following problems:
  • Poor print quality
  • Increased media jams
  • Premature wear on the printer, requiring repair

Properties such as weight, grain, and moisture content are important factors affecting printer performance and output quality. For best results, use only HP brand paper and print media. Hewlett-Packard company cannot recommend the use of other brands. Because they are not HP products, HP cannot influence or control their quality.

It is possible for media to meet all of the guidelines in this document and still not produce satisfactory results. This might be the result of improper handling, unacceptable temperature and humidity levels, or other variables over which Hewlett-Packard has no control.
CAUTION: Using media that does not meet with Hewlett-Packard specifications might cause problems for the printer, requiring repair. This repair is not covered by the Hewlett-Packard warranty or service agreements.
NOTE: Before purchasing a large quantity of media, make sure that it meets the requirements specified in this document. More detailed specifications can be found in the HP LaserJet Printer Family Print Media Guide ( click here to go to the Web site for the guide at http://www.hp.com/support/ljpaperguide ). Always test media before purchasing a large quantity.

Supported media sizes

The following are the supported media sizes:
  • Minimum: 76 x 127 mm (3 x 5 inches)
  • Maximum: 216 x 356 mm (8.5 x 14 inches)

Media to avoid

The HP LaserJet 1150 and 1300 series printers can handle many types of media. Use of media outside the printer specifications will cause a loss of print quality and increase the change of paper jams occurring.
  • Do not use paper that is too rough.
  • Do not use paper with cutouts or perforations other than standard 3-hole punched paper.
  • Do not use multipart forms.
  • Do not use paper with a watermark if solid patterns are being printed.

Media that can damage the printer

In rare circumstances media can damage the printer. The following media must be avoided to prevent possible damage:
  • Do not use media with staples attached.
  • Do not use transparencies designed for inkjet printers or other low temperature printers. Use only transparencies specified for use with HP LaserJet printers.
  • Do not use photo paper intended for inkjet printers.
  • Do not use paper that is embossed or coated and is not designed for temperatures of the image fuser in the printer. Select media that can tolerate temperatures of 200 degrees C (392 degrees F) for 0.1 second. HP produces a selection of media that is designed for the HP LaserJet 1150 and 1300 series printers.
  • Do not use letterhead paper with low temperature dyes or thermography. Preprinted forms or letterhead must use inks that can tolerate temperatures of 200 degrees C (392 degrees F) for 0.1 second.
  • Do not use any media that produces hazardous emissions, or that melts, offsets, or discolors when exposed to 200 degrees C (392 degrees F) for 0.1 second.
