Issue The All-in-One is working, but the printed output is not straight on the page. It is skewed or crooked. Solution Follow these steps to resolve this issue: Step one: Ensure that the paper is loaded correctly

1. To make sure that the paper is loaded correctly, check the following conditions:
   • The right side of the paper is even with the right side of the paper tray.
   • The paper guides are adjusted to the edges of the paper.
   • The paper is flat in the tray.
2. Make sure only one type of paper is loaded in the All-in-One.
3. Make sure the rear access door is securely installed.

Print a diagnostic page If no identifiable problem exists with the paper or the guides, print a test diagnostic page to see if the unit is operating correctly. Follow these steps to print a diagnostic page:

1. Load letter, A4, or legal unused plain white paper into the input tray.
2. Touch the Setup icon on the display.
3. Touch Tools .
4. Touch Self-Test Report . The HP All-in-One prints a Self-Test report, which might show the source of the printing problem.

Validate that the printer is within skew tolerance Follow these steps to validate that the printer is within skew tolerance using the self test report:

1. Fold the paper horizontally into half. Look through the paper to see the single and double lines at the top and bottom of the page.
2. The line over the single line and the line below the two lines should overlap exactly.
3. The single line at the top of the page should fall between the two lines at the bottom of the page.

Step two: Clean the paper rollers Follow these steps to clean the paper rollers:

1. Turn off the unit and unplug the power cord.
2. Remove the rear access door.
3. Wipe the paper rollers with a lint-free cloth lightly moistened with distilled or bottled water. Rotate the rollers with your fingers to clean all the way around.
4. Allow the rollers to dry completely, and then replace the rear access door.
5. Plug the unit back in and turn it on.

Step three: Service the printer If you have completed all the steps listed above and are still experiencing a problem, service the product. If this does not resolve the probelm I suggestsdownloading the HP Print Diagnoostic Utility:

Trust this will be helpful. :)

First you need to determine if it is optical skew or mechanical skew.
If the machine is used as a printer then do the computer prints come out skewed? If it is not connected to a PC then print out the counter list using UserTools/Counter. If that prints straight then you are dealing with optical skew. Ricoh's in general are bad about the left front corner of the machine drooping from someone pushing down on that corner. If you have optical skew try lifting up the left front corner of the copier and try making a copy. That might fix your problem.
If the UserTools/Couter print out is skewed then your back to a mechanical skew and there are numerous causes for that.
The optical skew is more likely so let's start there.

abt 1.89 liters.After I fill bikes .I always run it a moment to get the oil around everywhere, but no long enough to get it hot, which will skew the measurement. I let it settle back down for a half an hour.Then check the window again. It's always lower.Then top upto mark.

Well that problem is because there is not enought oil on the fuser roll. The problem is the oil pump. change it before make one irreversible damage to the fuser or pressure rolls. Do a full maintenance of the fuser module.

Hi!
Sorry about the delay in getting back to you. The problem has been taken care of. 1. The black cartridge was evidently dried up somehow. 2. The installation of the software (drivers & repair) (blue tooth or whatever) has completely fixed the problem. So whatever it was I paid for and downloaded at your suggestion (my ignorance of the jargon is minimal). However, what counts most: with your help, everything is operating and working as it should. Many Thanks! Raymond C. Root

your laser printer
1) print color quality is now distorted that means print skew (technician called)
2) print tint means the print color not enough density,
3) print mottle means print dirty
you may try
1) print distorted--- find out the skew adjustment from your printer manu, it is adjust the image before transfer to the drum.
2) print skew could be happened when the drum replace install not very accurate, so install it more carefully.
3) print tint---you may increase print density from the manu, not fix,
4) print tint---the toner caridge near life cycle or using the less compatible toner. so you have change the quality toner or cartridge (if near life cycle) to improve quality photo print
5）print mottle---toner quality ? or cartridge near life cycle also cause print dirty paper,

That is known as paper skew. It normally comes from A. Worn or dirty rollers either in or just past the paper tray.
B. The paper tray itself. C a spring off a roller not allowing even pressure on the paper, or D, the registration clutch which is responsible for stalling the paper long enough to square it in the machine.
For some reason the paper is twisting from uneven drive to the right side of your print as seen in the photo. Could even be a slight obstruction aka a piece of a label or tape that somehow is in the paper path causing the paper to drag in that area.
Normally skewing ( twisting ) of the paper it pretty easy to cure. I am suspecting with a 5 year old machine, some slick rollers first, then a spring/pressure problem on some roller.
Let me know, We can fix this one.

It sounds like the paper is skewing as it is picked up by the roller - watch a sheet go through and see if thst is the case. Make sure the paper guide in the paper tray is pushed solidly to the left edge of the paper and check if it is loose. If it is loose then it might allow the paper to skew as it feeds in
