Please take caution and follow the directions carefully. I also recommend that you take pictures for each step so that you have a visual record of the process.

Only HP Authorized service centre can repair this.
Get an estimate before you proceed.
May be a costly component.
It may be cheaper to buy a new printer than repair.

59 error indicates a main motor failure. This if often caused by a jammed cartridge, so trying a new toner cartridge would be your first step to trouble shoot this.

did you remove the barrier strip when you installed it? That can cause that but would normally trip an error on newer printers. Just because cartridge is new does not mean it cannot be defective,especially if you are using a 3rd party or reman cartridge.

If you have reused an IP address from an old or different printer then likely you have a stale print job that is spooling to the printer once you connect it and likely the driver is not compatible with the 2035. Try connecting the printer with a different address to see what happens.

When it start to peint blank pages ? after change toner ?

I'm not certain of this, but its possible that there are embedded postscript fonts in your document that are causing the printer to choke.
What I would do is to load up your file in Publsiher, and then save it as a Word.doc file. and then try to print.
I just looked at the service manual and this is the recommendation to try first.

You don't say specifically what printer you have (other than, presumably, an HP.) Is it always happening, or happening with specific print jobs?
SOME HP printers will let you increase the amount of memory in them.
Some have a setting in their driver that doesn't always match your installed memory - for instance, you may have 512 Mb but it thinks you only have 96 Mb.

Short term, turn off the printer, wait, turn it back on, see if it will print.

Juliet. Most likely the scanner lamp, or scanner control unit assembly is defective. If you're technically savvy, you could remove the scan glass and lube the shaft that the scan lamp assy slides on. Sometimes that will fix it. Otherwise, the whole top scan unit will need replacing. That could cost over $300 for the replacement.

you need to make sure that your printer is supported by TWIN , you can do that online.

Go to the Menu, Settings, network, Wi-Fi and under the menu navigate to see the SSID the printer is connected to.

I have taken this directly from the User Guide
"57 Fan error Turn off then on
Description - The product has experienced a problem with its internal fan.
Recommended action
Turn the product power off, wait at least 30 seconds, and then turn the product power on and wait for it to initialize.
If you are using a surge protector, remove it. Plug the product directly into the wall socket. Turn the product power on.
If the message persists, contact HP support."

For future reference this manual can be found here:
and being in pdf format can be saved to the computer.
Hope this is helpful, if so would you please register that with Fixya
