There is a CRC mismatch error in the toner bottle. Check the connection of the toner bottle or you replace the toner bottle.

Check for a code 42 , indicating that your printer has a cartridge region mismatch error. Turn off the printer. Leave it off for at least 20 seconds. Then turn the printer back on and try printing again. Confirm a cartridge mismatch. If the error code continues to appear, then check the printer and toner cartridge settings to identify which is not matching Determine if you need to return the toner cartridge for and get a replacement cartridge that matches your printer's geographic region.

The toner for the 9035 has a 'chip' to identify the toner is correct for the 9035, ie the toner is the correct manufacturer and model.
If you are getting the "ID Mismatch" error you either;

1. Have a faulty chip on the new toner cartridge, I guess the best option would be to go back to the supplier.
2. The toner cartridge is a copy / refill etc and has the wrong chip fitted, again going back to the supplier would be the best option.
3. Locate the contact for the chip on the new toner cartridge and ensure these are clean from any toner dust etc which may prevent incorrect contact with the printer.

"!" means error.

Try removing cartridge and installing it again and might be one of the cartridge missing.

Try operating manual. Might helps, there are lots of reason for the error

Yeah it is a problem with the chip that is on the cartridge. You can go to the Xerox.com site and contact them directly by phone or e-mail.
Just once at the xerox.com site, select your country.

Are you using a factory new ink cartridge?
Please consider the following:
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If you are using factory new cartridges, then please call the manufacturers Technical Support for assistance with the warranty on the cartridges

I was getting a similar blur/blob down one side of the paper (with no discernable print anywhere,) but after removing and emptying the toner collection bottle my printing returned to normal. I am still working on the size mismatch issue, which seems to be prevalent in the 2300DL population.

could mean that it a mismatch carteridge

The DVD region cannot be changed more than 5 times without 3rd party software which is very hard to find now as it has even been restricted in Europe.
You can look for "dvd region css free" online but you may not be able to get it anymore.

Good luck!
