Laserjet 4 standby/sleep mode
Have a LJ 4 with 1500 page count and was wondering can I upgrade this to incorporate a sleep mode that is on the HP LJ 4 plus by changing the firmware or ? I am at firmware 19921214. How about a swap of some parts from a scrap LJ 4 plus?
Thanks

If memory serves me there is no sleep mode available for the plain 4. Firmware could only be upgraded by replacing the formatter.
ZZZZ... Sorry, my sleep mode kicked in. DMZ is right, 4 had no sleep function. You can't swap the 4+ board into a 4 because of the engine speed differences. No way to upgrade the 4 formatter.
