HP PSC 750

I have an HP PSC 750,
and I too am getting the same old "Scanner Failure. So Please shut it down and then unplug it.
Well I do not have a re-fresh button like some of those guys say for me to do!
So this is what I found that has worked for me and hopefully for you all.
1. Turn off your printer and then UNPLUG IT!
let it sit for at least 5 minutes then repulg it. (if you do
not need it I sometimes leave it unplug overnight and replug it the very next morning).
This will help it to go into the refresh mode.
2. What is happening here is there is a memory set problem here.
What this printer needs for it to be RE-SET!
This is why we need to un plug it from time to time.

You see when you leave this printer on, it goes into a scanner memory by default 9 Why I do not know but this is my belief!), and when you all try to copy it does not want to go into this copy mode.
By unplugging it and replugging it this will re-set your printer to where it is like it should be.

Now if you are an electrician, you can put an on and off switch on this cord where it is easier for you to reach if your cord is too far buried for you to reach.

And if you are not an electrician...... Please get some help from someone who knows what they are doing and what you are going to do with this powercord for your printer. PLEASE!

NOTE: YOU MAY NEED TO ( UN PLUG AND REPLUG ) THIS MORE THAN ONCE, BECAUSE OF THE STUBBORNESS THAT YOUR PRINTER IS IN AT THAT TIME.

If you need any more help then you can e-mail me at "Maverick2842@sbcglobal.net"

Scanner error keeps coming up

I had this problem develop yesterday after 2 1/2 years of good service from this machine.

I found this fix

http://forums1.itrc.hp.com

Opening up the scanner and removing the large black plastic flap covering the scanner mechanism restored it to full working order.

Why I have no idea? Maybe the cover shifts and covers a sensor or receptor?

I was on the verge of running out and buying another machine!

service anon S750

Can't guarantee this will work, BUT don't deviate from this procedure. This worked on my Canon s630. Taking the printer apart is not that easy, you must work on the basis that the printer will be write off before start stripping it down.

Canon S750

Great site, hope I can find some help. My fairly old Canon S750 started acting up by banding and poor print quality. After replacing all the ink I am unable to get it to print at all. The lights were flashing orange 7 times then green once. Attempted resettting ink waste tanks following some instructions I found on this site but now printer flashes orange followed by green 7 times then once green. Any help folks? Thanks

I have error message on my S750 printer alternate green and orange and then a long green and repeats. Have you found out what the problem is or the sequence to reset it? If so I would like to know the problem or the solution. With my printer it will not shut off either.

Datamax M-class - turning off

I have a customer that has a Datamax m-4206 that will be working fine and then it just turns off. They have to switch it off for about 5 seconds and turn if back on. It will run for about and hour or so and then start turning off again. Is this the power supply or something else.

Thanks
