Hp laserjet 1010

Due to the problem with teflon in Hp laserjet 1010 . I went to the shop to replace the damage teflon. The shopekeeper replace the teflon . Printing is ok
but the printer is printing only 3 pages per miniute where it is printing 12pages per minutes(TEXT PRINITING ONLY)I try the two different OS but same result.
only 3 pages per minutes.
I want to know is it is possible that the shope keeper remove the internal RAM (MEMORY) of the printer. OR is there is any way to check the internal memory of my printer without opening it with any software help
