Black on all my color prints is slightly off!

You probably need to run an alignment procedure. See the link below.

Align Print Heads On An HP Laserjet 1600

Go to paint create black,cyan,megenta & yellow images & print it, observe which colors are not printing,If back missed replace black cartrige, if any color missed out of remain three replace colour cartridge.There is no option to switch off the catridges & printer can recognise the faulty cartridge and it will show on displays.
You can order cartridges online.

It may be that the ribbon is mispositioned. There are quite a few points in the trouble shooting section of the owners manual. These start on page 53. Here is the link to the page at the zebra company site that you can download the manual from.

Hi Aravind,

Are you using a refill cartridge? It would be best to allign after installing the cartridges?

Since most cartridges today have electronic contacts on them, if you dirtied them before installing the cartridge, it is possible that this could affect the performance, you might want to take the cartridge out and clean the contacts with rubbing alcohol.

Also, the alignment of the print heads may need to be adjusted, my hp requires this to make sure the color and black line up properly, otherwise you get a blurry image.

Furthermore, if the problem is with the color cartridge and you are trying to print a page of black letters and the printer is set to use colors, it may try to print the black using all of the colors instead of using the black cartridge. So you may need to clean the color cartridge as well. Try looking at the printing properties and making sure black is selected when printing something that is only text and see if it does it correctly then.
Good Luck!

Hey,
Your problem could be because of bad alignment. That means paper alignment and printer alignment don't match. There will be instructions in,your manual to properply align your printer. 
Hope this helps. 
Thanks

What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

Hello,

There are a number of single issues that can cause your problem in this case. The most common are listed below:
1.) Color cartridge expended.
2.) Print Paper selection incorrect.

From your statement above. I would suggest it is both item 1 and 2. Since, we are doing this assistance via chat mail, I can't come to your aid and witness myself what the results are and what your settings are for the paper type.

When you end up with a red hue over all over the print area the cause it usually a bad print head and selecting the wrong paper type.

To answer you question then, Yes, replace your color cartridge. But, first, try this method below to clean your color cartridge bubble jets.

When you go to print a job, always go into print setup or printer properties and choose the paper type as closely as you can to match the paper you are using.

The print head manual cleaning is listed below, it is from Lexmark. Below that is a process to clean blurry and bad print results. Although this is not specifically the case in your problem. The process to achieve resolution will also correct any problem your machine may be having. Remember, I do believe you need a new color cartridge. You will know with certainty however when you clean the cartridge head. If you do not see, cyan, magenta and yellow lines upon cleaning, at all, ever, then those inks are depleted. Replace your ink cartridge and then do these steps below the head cleaning.

Also, when ever you change a black or color cartridge you will want to run a print head alignment test and adjustment. There is enough of a difference in cartridges that this is quite necessary.

Please do not hesitate to give me as much feedback as possible on any issues and results you discover. You can use the comment text area below to respond to these instructions and give me the results of your tests and procedures.

Regards, Worldvet

To Resolve Print Quality Issues (below is for blurry lines, it will resolve many other issues too, so proceed after replacing your color ink cartridge if upon cleaning you see no ink coming out and the cartridge feels very light and makes little to no sound when you shake the cartridge.)

Overview This article outlines various techniques for resolving a blurry print issue. Cleaning the print cartridge nozzles is necessary when:

• Characters are not printing completely.
• White dashes appear in graphics or printed text.
• Print is smudged or too dark.
• Vertical, straight lines are not smooth.
• Colors on print jobs are faded, or they differ from the colors on the screen.

2. Open the Lexmark Solution Center (go to Start, Programs, Lexmark XXXX Series, Lexmark Solution Center).
3. From the Maintenance tab, click Clean to fix horizontal streaks.
4. Click Print. A nozzle page prints, forcing ink through to clean the clogged nozzles.
5. Print the document again to verify that print quality has improved.
6. If print quality has not improved, try cleaning the print cartridge nozzles up to two more times.

Clean and Wick the Cartridge

1. Try cleaning and wicking the cartridge to help improve the print quality. See this article for directions.
2. When this step is complete, try to run the clean print nozzles (CPN) operation again.

WORKAROUND: Select EconoFast or Draft as the print quality setting in the printer properties. This will prevent the color cartridge from being used. - Or - Try another color cartridge. The color cartridge is used to print grayscale images in Normal or Best print modes, so if one color has run out, the printout will have the wrong tint. With a full color cartridge, the colors can be properly combined to create a composite black. CAUSE: When printing with Normal or Best as the print quality setting, the HP Deskjet 710C or 720C or 722C series printer will use the color ink to improve print quality output, even when printing a grayscale image.
