Tech Tip VIII: HP 3330 Laserjet Warm Up Issues!

phoenixcomm

I have to warn you this fix is not for the faint of heart!
My Hp 3330 laserjet has been pushing paper for me for almost 20 years, without problems aside from every once in awhile changing the toner cartridge.image

About a week ago it would sit there making funny noises a the display stated Scanner Warmup. So I unplugged the printer and plugged it back in with the same results. image Since this is my only B&W printer I had two choices 1)  Buy a new printer (can't afford it), 2) use my Bother Color printer but the Black cartridge was dead! 3) fix the damn thing (hey I can fix jet engines!) So what the hell! When I Googled the problem, I got several hits (videos), and they explained that you don't need to buy anything. It is only the mirrors (in the black thing by the lamp) and they are most likely dirty. So you have to take the whole top apart. Control Panel and shroud, both side covers, and the upper side shrouds as well. This is like a bazillion screws so you will need a good mag tip Phillips screwdriver.

 

In step 15 you have to remove the plastic cover shown in step 16. There are square holes at each end. Use a pick to press down to release the clip.

Then Q-tips to clean the mirror frames (5), I cleaned them with Windex. But the glass deck was another story, hot water, and Dawn.

 

When everything was cleaned I put the glass deck in place and plugged it in. Eureka, it bitched about not having any paper in the tray!! image I then unplugged it for the last time and screwed it all back together. It is back where it belongs, on the stand, pushing Paper!!

 

Here is the video I used as a guide. Sorry, the guide was pulled on YouTube. So here is the blow by blow but no video you have to follow the pretty pictures! If you can't figure out how to reassemble the monster, start at #15 and go to #1.

    don't feel bad my office/workshop? has overflowed to my garage workbench with big tools ie. car tools, drill press, saws, most of my power-tools and whatnot. Plus I have a lest 3 AcroMills Bin boxes for screws nuts and bolts. All of the overflow is in my 10x40 storage building.

    Good guess, but it is a QMS ColorScript 100.

    I couldn't find a picture online, so I took one. The pen is just for size reference to prove it is a B size printer. It is missing the postscript interpreter, which is a flat box of the same footprint that sits under the printer. The box beside the printer has large rolls of ink, something like 300 pages x 4 colors per page, per roll.

    Please ignore the stack of "not-junk" behind the printer. This area of my hanger (basement) generally collects stuff to be sorted out, repaired, repurposed, stripped and salvaged. Or so I claim.

    You must have a small hanger to put your stash into. just for giggles is that printer a Xerox Phaser? I have a box of repair parts for them (cheap & shipping). I have them in my storage building that I will have to empty in the nex few months as I am consolidating as my car insurance just doubled.  

    BTW 68k stuff easy to fix everything is memory-mapped and there are no ports. you could put the Centronics interface on an Arduino Mega and define one 8-bit port as input (via interrupt control). The Interface is well defined.

    I save all motors, solenoids, switches, opto-couplers, gears, screws, washers, LEDs, buzzers, bearings, rollers, fans, power cables, fuse holders, heatsinks, magnets, springs (there are lots of springs) etc.

    Mostly I was interested in finding gears. The parts I have re-used most often are washers. I have used some springs and I occasionally find a use for some rollers and heatsinks.

    The process does increase the size of my stash but on the other hand it gets rid of something the size of a printer.

    I still have a laser printer, an ink jet printer and a big $10,000 thermal transfer printer waiting for salvage operations. At one time I had visions of refurbishing these printers. The postscript interpreter for the big printer is a Motorola 68000 based beast on a PCB that is about 20 inches x 20 inches. It died, but the printer can run without the postscript interpreter, if you have the right drivers and a Centronics interface - that is a big if.
