'carrier path blocked'

It could be the encoder strip which is responsible for the proper movement of the cartridge carrier in the carrier assembly inside the printer. Try to check to this article on the Lexmark website to give you an idea on how to re-seat the "plastic ribbon".
Printer Cartridge Stalls or Is Blocked

Try to open the printer cover and remove the cartridges. While the cover is open, check for a transparent strip(encoder strip) that may gotten unseated from its position. If transparent strip is still in position behind the cartridge carrier assembly, check the carrier path and make sure there are no debris or obstructions along its path.

hi

i need to know to the model of your printer

here is a link with that same message, just to give you an idea

Lexmark, http://images.lexmark.com/publications/pdfs/2007/3500/mhs/en/d0e10275.html

Here's the link to the Lexmark website on how to view the Lexmark Z645 printer User's Guide on your computer. http://bit.ly/aXZG9o. You might want to scroll down to Maintenance or Maintaining the printer for the instructions on how to replace the cartridges. If you won't be able to view it, try the steps below.
Make sure the printer is on. Lift the cover open. When the carrier positions itself in the center, open the latch. Reload new cartridges then close the cover.
In some cases, the ink cartridge carrier won't position itself in the middle even when the printer is on and the cover is open. Just unplug the printer from the power source. With the cover open, hold the white tape in the middle inside the printer. The other end of it is connected to the carrier. Gently slide the carrier to the center. Load the cartridges. Close the cover. Plug the printer back to power source. Hope this helps.
Leave a comment if you still need more assistance. Thanks.

Good day Sir, Please check the power switch light if blinking.

• power light blinking slow - printer is out of paper.
• power light blinking fast - there is paper jam in paper.
• once, pauses and blinks again - raise the scanner unit, and remove any objects blocking the path of the printer cartridge carrier. Or the print cartridge is missing/ not installed properly. Or the printer cartridge is not the correct type for the printer.

Have a nice day.

Unplug usb, delete old install, delete downloaded file, redownload file, run file, connnect USB when prompted.
