Copy off set

Print quality is good, b&w copy is good. When i make a color copy the machine makes blue lines or bink lines. This is a brand new c452.Scan to PC is ok, print its ok only copy. Lines are vertical.

The cover plate is above the glass white surface of the scanner. If this is the same dirty stains will come out on copies.
The glass must be clean.
By feeding the original documents through the ADF, the scanner lamp is no longer the path to scan, the ADF is responsible for passing the original document over the scanner, while it remains still placed on the side under a thin glass is to a large glass side. This also must be clean, otherwise you will be black lines on each point or spot on the glass.
Good luck ...

• 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.

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.

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.

When You Cannot Make Clear Copies

Hi,
platen glass means that you need to clean the copy glass - glass where you put the originals for copying.
If you have an auto document cleaner there is also small glass on left side of "platen glass" wich is seen when you open the copy machine cover or dadf.

The black line is probably from dirt on copy glass, I pressume because courectour liquid ( most common ). use some stronger detergent or wd-40 to disolve the dirt and clean with glass detergent and dry it.

If you still have the black line try to print something from machine.If you do not have it on print its the copy glass problem - clean it - again.

Pls.rate

Please answer to help you.You need the position correctly the problem source.

This has a happy ending. But first, the obligatory narrative:
The HP site has advice on how to deal with a document feeder that doesn't detect your document. It doesn't talk about the opposite problem, which is what molecular is describing. I had the identical problem yesterday. I'd place the original on the glass and it kept demanding that I put the original in the feeder. So I got into a chat session with the HP technician. Her advice, (based on the possibility that a power surge had created the problem) unplug from everything, restart, and retry. The problem persisted. I told her so. She broke the connection. Nice.
So here is how I fixed it. Using the Setup button>Tools>3. Restore factory defaults, I returned the device to its factory settings. I put the original on the glass and it made the copy without a problem.
Here is a pure speculation. There are at least two ways to enter settings related to two-sided copying. I had used one to enter the settings (two-sided original to two-sided copy, as it happens) and later tried to use another button to change those settings. I noticed the 2-sided settings did not change. I believe the feeder is the default for two-sided copying. So when the system failed to clear the settings, it failed to clear the default. Once I returned all settings to the factory originals, the problem disappeared.

If you just changed the toner cartridge, you probably forgot to remove the metal foil seal, from the side of the new toner cartridge.

The small scanner glass (not the full size glass) has some dirt on it. Use a lint-free cloth (not paper) with alcohol or Windex and clean the glass. This should help.
