Hi Albert,
Yes I noticed that. I need the 50V range more than the 2500V. But 100V will suffice for most ceramic & poly caps.

Hi Gerald. Since you already use 180 gram A4 sheets, you probably won't have to worry about using thicker paper in your Laser printer. And Robert is right of course. He is never wrong by suggesting keeping out any dust by covering the top. I luckely don't have have cat hairs, because I do not have any Pets at home. But I'm even very carefull before just inserting DVD's in my pc dvd burner or dvd tv recorder, as I always inspect any new dvd on its recording layer for dust particles. And blow them carefully clean with some air without touching.
It saved me from many bad DVD recordings.
(And looking for any bad spots is always a good thing).
By-the-way Robert if you read this...You mentioned that you are glad your Digital insulation meter starts at 50 Volt Range. My ordered meter starts at 100V although I thought it was the same one as you had bought. But therefore my meter meassures higher upto 2500 Volts I guess ? (I wanted to react on your comment after that article but it somehow wasn't possible, so I reply here.)
Cheers.
Albert.

Thanks Albert for your words of confidence. Of course the repair is more difficult when you can't get any manuals.

Thanks for your reply Albert. Totally agreed with you. Actually I am printing relatively thick paper (180 gsm) when I make panel layouts for my prototypes.
Anyway, as Robert wrote, better use a plastic cover when the printer is not used.
Cheers,
GM

Hi Robert !
I am sure that if you ever engage fixing your first not working printer, there will be no better person suited for the task.
You probably also have much more patience than I have.
Printers are just not my thing. (to messy and dirty most of the times).
Greetings,
Albert.

Hi Debirt Maynard, I am glad that you didn't throw your HP printer out!
You did manage to fix it after all !

We, my friends and I, have a saying in The Netherlands, that if we hate some not working product or device, we throw it out. And our friends mostly reply in that case, asking in what direction we are planning to throw. That way he knows how to grab it for himself (Haha).

I myself have still about three now unused HP printers at home (1x HP720C and 2x HP840C all old and the 2 840C bought cheap on a fancy fair), but all with empty cartridges. So now I use a Brother 385C without the empty cartridge problem (never empty and always working fine ! Just great !!)

Hi Gerald, I can't guarantee that it will also work on a laser printer.

Because I just don't know if you are able to remove the inserted hardcover A4 sheet from your laserprinter afterwards.
On the MX320 I could easily remove the hard A4 size paper/cover from the Canon printer.

So if you try this be sure you don't risk more damage. (read your manual before trying this if it handles these kind of thickness)
A laserprinter has more delicate parts, you see. As you got Laserunit, TonerUnit and a Heater unit that heats up the paper up to about 80 degrees Celsius. And if the paper turns over internally on rollers it could be a problem.

Cheers.
Albert.

Thank you for your advice Alphonsus.
I only did this solution once up to now, and if it doesn't work a second time it must be some sticky part on the rollers as you say. And if it just are little particles like paper shreds or this case maybe cat hairs it probably still will work another time too.

Opening a printer when there even is no backdoor to remove any paper jam is a harsh job.
Greetings.
Albert.
