While Lexmark is an excellent printer and one of the most popular solutions for office and even home use, any printer can run into problems over time, or, if you're not that lucky, even after you've used it. Unfortunately, Lexmark printer repairs are expensive. The good news is there are a number of things you can do to make sure your printer stays healthy. If you want to buy Lexmark printers online then you are in the right place.
To avoid repair, replace the ink as soon as the printer warns you about ink shortage. If you slow down and run out of ink, the output jet resistor may overheat and damage the printheads, and/or produce unmarked output.
Also, do not leave open cartridges open or fill them indiscriminately for any reason. Any process can cause a cartridge to clog, which can damage your printer.
Lexmark Optra laser printers (as well as other brands such as Hewlett-Packard) require periodic maintenance kit replacement after a number of pages have been printed. Lexmark introduced the Optra printer service kit in the 1990s. Today, most Lexmark printers (with the exception of low-end and therefore less complex service kits) require between 150,000 and 250,000 printed pages. You will need to check your manual for the number of pages showing "maintenance errors."
Problems such as unwanted lines in printing and paper jams are relatively easy to solve by replacing or adjusting the toner and manually clearing torn and jammed paper from the printer.
