HP printer covers are a hot seller for parts suppliers like Metrofuser. Why? many covers are damaged during the printer repair process. HP printer covers are interconnected meaning they need to come up apart in order and reassemble in order. Much of this damage is avoidable with simple precautions.

Our engineers remove and reinstall over ten thousand HP laser printer covers every year. We have learned printer cover replacement is part art and part science and we will cover both in this article.

While Metrofuser has many how to videos on specific repair and printer parts replacement we wanted to develop a video to cover general printer cover removal and replacement. This video and article are designed to help HP printer technicians remove today's laser printer covers.

Two biggest problems when removing HP printer covers

  1. Damaging the printer cover.

  2. Removing to many covers takes more time unnecessarily and increases the chances of breaking a cover.

In general HP laser printer covers are interconnected by a tab lock system, flat head or phillips head screws or some combination. Typically the smaller desktop printers utilize a tab lock system while larger work group laser printers utilize screws.

HP printer service manuals as wells as Metrofuser's blog have exploding diagrams of hp printer covers. Take a look at one here Part Diagrams-M607 M608 M609 HP Laser Printers.

Steps for HP printer cover removal

  1. Observations

  2. Ask questions - How are the covers interconnected?

  3. Locate the connections

  4. What types of connections? Tab Locks or Screws?

  5. Begin removal process

Where to begin

Open the printer toner access door. This point on the printer will give you allot of information and clues on how the printer covers are interconnected. Removing the top cover reveals the screws and more information on how to remove the side covers.

Before removing the top cover locate the door hinge and disconnect it. Next locate screws that going thru the cover. The screws are usually in the top or bottom of the panel.

Working with the printer cover tab locks

When working with HP printers with tab locks check the service manual to see what direction to direct the pressure with the flathead screw driver. Every printer utilizes the locking tabs differently.

You can utilize a technique of holding the cover with one hand while directing the pressure of the flat head screw driver with the other hand. Push directly in first while feeling if cover is becoming loose. If not direct the pressure down and in, while feeling the cover. Then up and in and so on.

Our demo printers are the M605 and M401. These two HP models have similar printer cover removal properties found on most HP laser devices.

The art of the use of force

Biggest question how pressure should a printer technician use during the removal process. Start with as little as possible and slowly increase. You dont want to scratch break or scrap the plastic cover.

  • To little force and you wont be able to remove the cover.

  • To much force and you can damage the cover or frame.

How avoid stripping the screw or the printer frame

  1. Pick the right screw bit

  2. Hold it right

  3. Insert by hand and rotate the screw counter clockwise (yes wrong way) until you feel and bump in the screw path. That means you hit the beginning of the screw thread. Next turn the screw by hand clockwise until you get a feel it grip. Now start using the screw driver.

Avoid over tightening

When tightening printer cover screws, it is critical that you do not over tighten and crack the cover. Turn the screw until you feel slight tension. Grab the cover and gently pull and listen / feel to see if its loose. If it is turn the screw slightly again and repeat test again.

To late. I damaged the printer cover now what?

The good news is just about every cover for HP laser printers are available for replacement. Locate the printer cover part number from the exploded hp printer diagrams.

Solving The HP Laser Printer Cover Panel Discoloring Phenomenon

The HP Laser printer yellowing problem can make a great working printer look like it needs to be replaced. For many printer service dealers and managed print services MPS providers this could be a problem.

The phenomenon shows up on HP laser printer covers some looking as new as the day it came out of the factory, others will turn varied shades of tan yellow or even gray.
