Two biggest problems when removing HP printer covers
Damaging the printer cover.
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.

Locating the printer cover tab locks.
Look for triangles on cover (fig 1). The triangles are symbols that tell the printer technician where the tab lock are located. Gently use a flat head screw driver to pry the tab lock.
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
Pick the right screw bit
Hold it right
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?
