I have a lexmark prospect pro 200 series printer and there is an error message that reads "There is a problem with the printhead. Please consult User's Guide."

If you're getting that error message, the printhead would need to be replaced. If your printer is still under warranty, please call our technical support team to have the printhead replaced.

If it's already out of warranty, you can purchase a printhead here: http://bit.ly/IZYhWo

Try to clean the contacts of the printhead and the printer. If it doesn't work, unplug the power of the printer for about 30 seconds and plug it back in.

A firmware update for your model addresses the print quality problem you are currently experiencing. Please visit the Lexmark website to download and install the Lexmark Pro200 Series Firmware Update.
Should the error continue, then it could be a faulty printhead issue. Please contact Lexmark Technical Support Center to have your printhead replaced.

A firmware update for your model addresses the print quality problem you are experiencing. Please visit the Lexmark website to download and install the Lexmark Pro200 Series Firmware Update.
