The HP 2605DN Color LaserJet Printer currently retails, used, for around 290.00 dollars. While it markets itself as "an affordable desktop printer that lets you add brilliant color to your business documents," if you take some time to read the reviews, you'll uncover that what you bought might not actually be so reliable. After only printing a few hundred hundred pages, many reviewers have reported that the red/magenta tones have faded, even when the ink cartridge is not close to empty. Obviously when one ink shade malfunctions, your entire color document also suffers in quality.
If you have this printer, you might wonder what is causing the problem. Though some have reported that HP Customer Support has been unhelpful, support forums have diagnosed the problem as "a design flaw in the Canon engine used in some HP color laser printers: dust accumulates on the mirrors deep inside the printer and causes colors to come out poorly. Because the magenta cartridge's mirror is on the bottom in this model, it gets the most dust." Thankfully these same users have reported fixes to get those reds vibrant again, even when HP has been unhelpful.
If it's your first time opening up a printer to make some internal fixes, you will want to consult this step-by-step manual, ensuring that all screws and working parts are returned to the proper place. Failure to ensure these parts go back in the proper order can result in other issues with your printer apart from those annoying fading reds. For those who are seasoned veterans at printer repair, you will to do the following:
- Remove the right, left and rear covers. Many of the screws are small and in hard-to-reach places, so be sure to have a 3-mm compatible screwdriver.
- You'll have to remove all of the wire plugs from the for-matter and DC controller. If you're unsure which plugs you're not supposed to pull, please consult the step-by-step instruction manual.
- You'll have to remove more internal screws to gain access to the scanner mirrors and lenses where the dust has accumulated.
- When cleaning the internal mirrors and lenses, be sure NOT to use any cleaning solvents unless specifically necessary, as directly rubbing the optical surfaces may cause damage. Instead, try using dry cotton swabs and compressed air.
- When returning all parts to their original position, be sure that all parts fit in firmly and in their correct slots before tightening screws. Misalignment can affect printer quality.
If the task seems too daunting or difficult (let's face it, not everyone is a mechanical whizz!), don't hesitate to take it to your nearest electronics repair specialist. Though it may cost extra, the price of having a working red/magenta ink cartridge is important if you want to have any success printing color documents from home.
