Re: Dumbest thing u have seen a tech do!

That reminds me of a tech I knew that paper clipped both thermal fuses on a Mita DC-142RE. I was rebuilding that fuser two years after his exit from the company. I discovered the clippage, but that's not the best part. It was at a fire department. How long do you suppose it would have taken for a fire investigator to find it, in the ashes of the fire station? =^..^=

2 years and no fire,luck was on that techs side.

I go to machines so often that a previous tech has hit and run and sprayed Q20 into the clutches and transport section bushings,the only thing to do is replaced all the clutches and strip and clean the now sticky toners out of the bushings. It still beyond me that guys thinks oil in clutches stop paper jamming.

I tried that once on a Ricoh 3025. Not a good move at all.

Re: Dumbest thing u have seen a tech do!

Back in the day when Lanier was switching from analog Toshibas to digital Ricohs, I got a call on a 7320 (analog Toshiba) that wouldn't turn on. I got to the place, and besides the machine not turning on, a bright blast of plasma would come out from the bottom of the power switch when it was turned on. It actually looked kind of cool to me, but that's beside the point.
Turned out someone had installed a Ricoh thermostat in place of the Toshiba thermofuse, and the thing was shorting out to the fuser frame.
Actually that must have worked for a little while as the other tech got out the door. I never found out who the other tech was, and I really wasn't that interested either as the machine was located in a bakery and they gave me cookies for fixing their machine.

Free cookies fix everything.

It still beyond me that guys thinks oil in clutches stop paper jamming. [ quote from earlier thread by Brett GS ]

I agree with that statement for electronic clutches, but for spring or wrap clutches, grease is a must or jamming or outright failure of the clutch will occur. The springs without grease will not release properly and bind and tangled. Some clutches use a combination of electromagnetic and mechanical wrap spring to function
[ kyocera falcon 2 bypass pickup clutch as an example ]. Techs just replace them instead of repair, or spray the magic oil, thus the clutch works for while and then fails because grease should be used to lubricate those springs and not oil.
Next time you are to install a spring clutch, disassemble it and examine it and some will be lightly greased and some packed with grease, but you will never see them dry.

What grease do you suggest?

Below is a SHARP part number and description.

UKOG-0238FCZZ
FLOIL G-484

Semi Transparent grease
Primarily used for lubricating wrap spring
clutches.

I use LUCAS heavy duty bearing grease. A small tub should last you a lifetime.

Good old wheel bearing grease. Tried that on a C452 fuser once.

I just remember, not a long time ago, doing a fuser film replacement on a HP printer I noticed a familiar bronze paste instead of fixing grease. It was processor thermal paste.

Re: Dumbest thing u have seen a tech do!

hi all
we all got some memorable moments, I am sure some more then others.
my was with Sharp SF-8300 old machine. The fans were installed wrong from factory, on some units
it was sucking the air in, and it needed to blow it out . the easiest way to test the fans was with the lighter.
you put the flame near the cover and you can easily see which way the flame bends.
in my case it sucked the flame in on to the filters, which started to burn. not a nice feeling
that was when I stripped that cover faster than any other cover ever. to remove the smouldering filters.

The company I worked for hired on a tech, we sir named " Bangs and Brows," within the first week, he managed to singe off some of his bangs and eyebrows. He was cleaning the back of a Sharp 8250 with canned air and blew it into the fuser. I will never forget him walking into the door with a dumbfounded look on his face and missing hair. A month or so later, after his bangs grew back in, he was working on a Sharp 2118/ 2020, if you have ever worked on those pigs, I'm sure you can remember when the adjustable lens would skip a gear tooth or two, due to lack of lubrication on the rail. Well, apparently he was not aware of this known issue, and instead of lubing the rail and aligning the lens back to home position, he proceeded to to adjust the mirrors in the dark box to compensate for the blurry copies and never bothered to adjust the lens. I was the tech that was called out after him, now the problem was the copies were blurry when they enlarged or reduced. Upon arrival, I installed the lens back to home position and lubed the rail, now all the copies were blurry, so I called " Bangs and Brows" and asked him what he had done, his response to me was " I just cleaned the copier" and that was it. I spent about two hours on it, could not get the copies into focus, so I picked it up and brought it back to the shop. The next day I was working on it and " Bangs and Brows" came over to my station and asked me what I was working on. I told him the copier with the blurry copies, he still did not mention a word to me about any "modifications," he made. I worked on it for a couple more hours and discovered the mirrors in the dark box had been moved out of home position. I called up " bangs and brows' and asked him if he moved the mirrors, he then acted surprised and admitted to me he had been to the call for blurry copies and adjusted the mirrors in the dark box, I couldn't believe it!! Well, needless to say he wasn't there much longer, apparently, he wiped out a Sharp 9750 drum with a paper clip the was stuck to the dev. unit after he cleaned the copier. I will never forget " Bangs and Brows" as long as I am living, looking back on it now, makes me laugh every time.

I didn't see it, but customer caught the tech jerking his meat in the supply closet.

Must have been a newbie. They tend to get really excited when they figure out something on their own. And you should be happy you didn't see it. Poor customer will have that vision every time he goes to that closet.

He saw something or someone in there , got lost in a trance and had a zen moment, out of control. couldn't wait till he got home.

yeh, i has a good laugh at this one and shared it with the kids at work.
