Prints jibrish eg. unrecognizable characters and signs. What is wrong and how do I fix it?

Certain punctuation symbols, extended characters (if a non-US / non-UK keyboard), are not allowed.
Offhand, I can't remember all the 'banned' characters, but for example, the at @ symbol colon : symbol direction arrows <> and period . may be confusing to url's.
If you can use another computer or smartphone, try googling 'valid characters for email' or ' how to set up an account'.
Specify the account type, eg: Gmail.

The hammer, ot the actuator will be defect. Replace the whole machine.

Find the at sign on your keyboard, or use the table of characters in the accessories menu.

Go to Preferences, then general, then Digitizer.

You need to recalibrate the digitizer.

It will ask you to tap in two opposite corners, then at a target in the center of the screen.

Should fix you right up

there is nothing wrong with the printer ... the issue is the support in your computer for those languages...

Sounds like you have tried all the easy stuff. I'll guess that the gear on the selection plate is loose from the shaft. No easy fix, you may be better off buying a replacement on ebay they get pretty cheap.

Your keyboard assembly needs to be replaced.

it depends on the type of paper you are using.

ink chemicals react to the chemicals on the photo paper.

manufacturers have ¨recommended papers¨ : )

recommendation: ask for paper samples from paper vendors

First when you see that first page come out like that...turn the printer off. You will need to re-install the printers drivers. (the CD that came with the printer)

Does it always type the same wrong letter ie a always prints u or w ? if so the print wheel drive gear is out of position. if not and it get random letters some thing may be interfering with the wheel rotation.
