In the very first step, move your printer in a proper ventilated area and then arrange cleaning rags, alcohol and a screw driver.
• Then in the second step you need to detach the top lid and the inner lid of the printer.
• Then, hold properly the handle of the Ink cartridge lever and then pull it out for unlocking it.
• From the holder, unclip the printer roller and then clean it properly using a wet rag. For cleaning the rollers, try using the rags dipped in alcohol.
