Print darkness Copies are too light even when adjusting density darkness level. Are there settings in the copier that can be adjusted?

There are a few potential reasons why your copier might be printing faint copies:

1. Low toner levels: If the toner in your copier is running low, the copies it produces may appear faint or light. To fix this issue, you will need to replace the toner cartridge.
2. Dirty or clogged nozzles: If the nozzles on your copier's print head are dirty or clogged, they may not be able to produce a full, even layer of toner on the page. To fix this issue, you can try cleaning the nozzles or running a nozzle check to see if any are clogged.
3. Wear and tear on the print head: If the print head on your copier is worn or damaged, it may not be able to produce copies with the same intensity as a new or well-maintained print head. In this case, you may need to replace the print head to fix the issue.
4. Incorrect print settings: If the print settings on your copier are set to a low quality or low density setting, the copies it produces may appear faint. To fix this issue, you will need to adjust the print settings to a higher quality or density setting.

If none of these steps resolve the issue, it is possible that there is a malfunction or defect with the copier that will need to be addressed by a professional. In this case, you may want to consider contacting the manufacturer or a customer service representative for further assistance.

See "Adjusting Copy Image Density", Copy and Document Server Reference . The reverse side of an original image is copied. Auto Image Density is not selected. On the control panel, select [Auto Density]. A shadow appears on copies if you use pasted originals. Image density is too high.

• Adjust the image density settings. See "Adjusting Copy Image Density", Copy and Document Server Reference .

• Put mending tape on the pasted part.

The same copy area is dirty whenever making copies. The exposure glass, scanning glass, or ADF is dirty. Clean them. See "Maintaining Your Machine", About This Machine . The same copy area is dirty whenever making copies.

• The original that has already been printed is scanned.
• Original Type is set to [Text / Photo], and an original with text and photographs that can hardly be distinguished from each other is loaded.

On the control panel, press [Generation Copy], and then begin copying. Copies are too light. Image density is too light. Adjust the image density settings. See "Adjusting Copy Image Density", Copy and Document Server Reference . Copies are too light. A light copy may result when you use damp or rough grain paper. Use recommended paper only and be sure its storage environment meets the recommended temperature and humidity conditions. For details about recommended paper and the proper way to store it, see "Recommended Paper Sizes and Types" and "Paper Storage", About This Machine . Parts of images are not copied. The original is not set correctly. Set originals correctly. See "Placing Originals", Copy and Document Server Reference . Parts of images are not copied. The correct paper size is not selected. Select the proper paper size. Parts of images are not copied. Even if you place originals in the ADF correctly, margin of a few millimeters on all four sides of the original might not be copied. Use "Create Margin" function to reduce the image of its original size.
For details about missing image area, see "Missing Image Area", Copy and Document Server Reference . images appear only partially. The paper is damp. Use paper that has been stored in the recommended temperature and humidity condition. For details about the proper way to store it, see "Paper Storage", About This Machine . Black lines appear.

See "Maintaining Your Machine", About This Machine . White lines appear. The dustproof glass is dirty. Clean the dustproof glass. See "Cleaning the Dustproof Glass", About This Machine . Copies are blank. The original is not set correctly. When using the exposure glass, face the originals down. When using the ADF, face them up. A moir? pattern is produced on copies. Your original has a dot pattern image or many lines. Place the original on the exposure glass at a slight angle. Black spots appear on the copy of a photographic print. Because of high humidity, the photographic print has stuck to the exposure glass. Place the print on the exposure glass in either of the following ways:

• Place an OHP transparency on the exposure glass, and then place the print on the OHP transparency.
• Place the print on the exposure glass, and then place two or three sheets of white paper on it. Leave the ADF open when copying.

White stripes appear on the OHP. Fragments of paper are stuck to the OHP. Use a dry cloth to wipe any paper fragments off the back of the OHP. The image on the back side of duplex copies has mottled blank patches or is smudged. Missing patches and smudges are caused by moisture leaking from the paper.

• Do not install the machine in areas that are susceptible to low temperatures.
• Use paper that has been stored where temperature and humidity conditions meet the limitations we recommend. For details about the paper storage conditions we recommend, see "Paper Storage", About This Machine .
• Install the Optional anti-humidity heater. For details about the anti-humidity heater, contact your service representative.

Also see the Troubleshooting section of the User Guide for other possible reasons for light/faded copies.

If your copies continue to come out too light, you may need to clean the insert a new toner cartridge or change brands of toner. I tried several "generic" toner cartridges and refills, but my prints and copies were always faded or streaky. After going back to genuine HP cartridges, I haven't had any print quality problems.

It's been a long time since I worked on of these machines. I believe under the additional function option there is adjustment option for image density. This should overide current copier density settings. Sorry I can not remember exact naming.

When you print, use file/print. When the dialog box appears select print properties and adjust either the quality or the darkness setting, click apply

I'm having the problem too in addition to not being able to print on both sides (duplex printing).

When using generic toners, the automatic setting doesn't adjust to factory specs. So you have to adjust it manually. If you are using OEM toners the there is an issue with the density settings, and the unit needs to be adjusted by a tech.
