Print-quality examples

General print-quality issues

The following examples depict letter-size paper that has passed through the product short-edge-first. These examples illustrate problems that would affect all of the pages that you print. The topics that follow list the typical cause and solution for each of these examples.
Problem
Cause
Solution

The paper might not meet HP specifications.
Use paper that meets HP specifications.
The print cartridge might be defective or low. If you use a non-HP print cartridge, no messages appear on the product control panel.
Replace the print cartridge.
If the print cartridge is not low or empty, inspect the toner roller to see if the roller is damaged. If it is, replace the print cartridge.
If the whole page is light, the print density adjustment is too light or EconoMode might be turned on.
Adjust the print density, and disable EconoMode in the printer driver.
Toner specks appear.
The paper might not meet HP specifications.
Use paper that meets HP specifications.
The paper path might need cleaning.
Clean the paper path.

Use a different paper, such as high-quality paper that is intended for laser printers.
If characters are incorrectly formed so that they produce a wavy effect, the laser scanner might need service.
Verify that the problem also occurs on the configuration page. If so, contact HP. See www.hp.com/support/ljm1130series or www.hp.com/support/ljm1210series or the support flyer that came in the product box.

Scan-quality problems

Prevent scan-quality problems

The following are a few simple steps you can take to improve copy and scan quality.
  • Use high-quality originals.
  • Load the paper correctly. If the paper is loaded incorrectly, it might skew, which causes unclear images.
  • Adjust the software settings according to how you plan to use the scanned page.
  • If your product frequently feeds more than one page at a time, the separation pad might need to be cleaned or replaced.
  • Use or make a carrier sheet to protect your originals.

Solve scan-quality problems

Problem
Cause
Solution
Blank pages
The original might have been loaded upside down.
In the document feeder, put the top end of the stack of originals into the document feeder, with the media stack face-down and the first page to be scanned on the bottom of the stack.
Too light or dark
The resolution and color levels may be set incorrectly.
Verify that you have the correct resolution and color settings.
Unwanted lines
The document-feeder glass might be dirty.
Clean the scanner strip.
Black dots or streaks
The power to the product might have fluctuated.
Reprint the job.
Unclear text
The resolution levels might be set incorrectly.
Verify that the resolution settings are correct.

Repetitive defects ruler

If defects repeat at regular intervals on the page, use this ruler to identify the cause of the defect. Place the top of the ruler at the first defect. The marking that is beside the next occurrence of the defect indicates which component needs to be replaced.
If the defect correlates with the print engine or the fuser, the product might require service. Contact HP Customer Support.
