LaserJet 4 cleaning problems

Got some LJ4 printers in my school that were working fine, but needed cleaning. After removing side and top, removing fan, and brushing/vacuuming all parts, units were reassembled. When plugged back into computer they will only print out blank pages when running test or trying to print. No problems before cleaning. Anyone have any suggestions? Also, can anyone tell me how to check number of total pages printed by LJ4 and LJ5? HP site says look in manual, I can't find it. Thanks in advance for any help.
Are you getting any kind of error codes on the display? Did you try doing an engine test (see troubleshooting section)?
