Thread: HP PSC 750 bp

Here I have a problem with my HP PSC 750 who is 4 years is a multifunction (printer-scanner-copier).

Nickel printer side But lately I have a problem with the scanner and thus the photocopier.
As soon as I copy I preheat for 1min and then I get the message <<echec ISDN disable then re l'appareil>>

I already tried the following methods I found on internet but still nothing.

Method 1

-Unplug the power cord from the printer without turning off.
-Press the button "ON / OFF" or "ENABLE" ten seconds.
-Release the button, and reconnect the cable.

Well yes, I have exactly the same problem as you with an "old" HP Office Jet R45 "all in one! It seems to read on this forum, it is almost impossible to find on the HP site or anywhere else a driver! I will try your method without much hope otherwise, as others write, I think we are good to buy another scanner!

I have the same problem: "Numeris failure." But I still sumptuous quality photocopy draft. And it does not work. I unplug the cable behind. I wait 10 seconds. I reconnect. I'm waiting for it to do its weird noise like how it initializes. I run the copy in normal mode.It starts as it should Cancel. I called into draft quality, and it works.

We realize that reading forum HP printers all have the same problem for generations. New or old, the scanner fails. Electronic problem, scanning, ...These are not mechanical problems, but electronic. The programming of these failures is quite easy.

Each manufacturer has a quality department and know precisely the sources of failures. If it does not solve it entirely because these failures are intentional! Ask for a discount on a new machine, a free repair or change to another brand. Consumers must act to influence the decisions of these firms.

I tried cetteméthode but it only works up to "cancel copy" when I press the button to fast mode (ie draft) I have a message on the screen printer "busy" in fact most can jene press 1 after another button after pressing the button "cancel".

I bought a new printer but it does not mean throwing the other because the print function still works. I took the photosmart 2575 she is very beautiful with a color screen and swivel it scans and copy not seen in years!

Exactly the same problem for my HP 750 buy about 4 years ago. For me the decision is made, I change hardware (I keep it anyway it works in printer mode) and manufacturer.

But after removal, indeed, as some have pointed out on other forums: the reflector (plastic strip placed behind the mini tube) is to be merged. Suddenly, the light is no longer sufficient QED.

For my part, I have not coated reflector with white correction fluid. I opted for a spray of color heater (high temperature) white. NOTE WELL protect around the reflector does not put on the mirrors.

I just met the same problem. I tried unsuccessfully to reset the apparail proposed by various manip here and there. For me the art of dismantling glass with a good cleaning has paid off, I contented myself to spend washing windows on both sides, I don 'have not touched the mirror.

You must remove three or process being appointed Quattra HPxxxxx (they déactivent in the task manager (ctrl + alt + supp)) before launching the HP software. It worked with me!
