Question about Konica Minolta magicolor 2550 Laser Printer

Open Question

The LCD display stopped working. The printer works fine.

I've power-cycled it once or twice, and it doesn't make a difference. The display is just blank. I don't see anything amiss, although I haven't taken it apart.

If the iron doesn't heat, make sure 1) power is on to the outlet, 2) check the electrical cord and 3) check the thermostat and replace if necessary. Use the VOM.

Acer Aspire 5536 only gives black screen when i connect power supply


  • Nothing is more annoying than a monitor that refuses to turn on. Make sure your Acer monitor is plugged in to a functioning outlet. If it's plugged into a power strip, try replacing it with a new one or moving the plug to a different outlet. Ensure that both ends of the power cable are plugged in firmly and securely, and that the connection to the monitor is not loose.
Cable Issues
  • Your Acer LCD monitor will usually accept DVI and VGA inputs. If you have an older computer, a VGA cable should work fine. If it doesn't have a VGA port, you'll need to obtain an inexpensive DVI to VGA adapter at your local computer store. A DVI cable, however, is compatible with most modern computers and offers superior picture quality over VGA. Make sure you're using the cable that's compatible with your system, and that you have the proper conversion adapter, if necessary.

Both of my ink cartridges went out at the same time and i only replaced the black. now it has an error saying it will not print because i need to replace the color ink cartridge. but i'm trying to...


It depends on the model that you have. You can try one of the following to reset the ink counter and the printer will show a full color cartridge.

This is the procedure I used for an MP470. It is basically a modified version of that previously posted for the MP460.

1. Disconnect the power cable.
2. Hold down "On/Off" button.
3. Reconnect the power cable.
4. With the power button still down, press the "Stop/Reset" button twice.
5. Release the "On/Off" button.
6. The printer is now in "factory mode".
- wait until "idle" is displayed.
7. Press the right arrow button (next to the "OK" button) repeatedly until "Shipping Mode 3" is displayed.
8. Press the "OK" Button
9. Wait until "Without Cleaning" is displayed and then presss the "Stop/Reset" button once. (I pressed the ok button after Stop/Reset button on my MP470).
10. A test page should print.
11. Open the cover.
- the cartridges should position themselves at the far left - the cartridge removal location.
12. Disconnect the power cable.
13. Remove both cartridges.
14. Close the cover.
15. Reconnect the power cable.
16. Press the "On/Off" button once.
17. Wait until a "Replace Cartridges" message is displayed.
- insert cartridges.
18. Wait until the printer is operating in its normal mode. The display shows the normal start menu (ie: Copy).
The ink levels have been reset.
- check by going to printer>properties>maintenance>view printer status

12. Disconnect the power again

14. Close cover
15. Reconnect power cable

I have an HP 7410 with the error message "remove and check color cartridge." The circuit board behind the cartridge is not damaged, and the side-load spring is intact, so that's not the...


Sounds like the mainboard inside of the printer is bad.
Some things to verify this, make sure the cartridges that your using are original HP Cartridges and NOT 3rd party ones, even though 3rd party can work, its hit and miss and can cause sporadic problems.
If that doesn't fix it then try this troubleshooting step:
Reset process is........unplug power cable from the back of the unit, without turning it off, wait for about 10-15 secs & then while plugging in the power cable press & hold # key & the 3 key.....once u can see the unit powering on let the buttons go. Its important that you do the plugging in of the power cable while your holding these buttons on the printer........you will see a "partial reset" being displayed on the printer.
If that does not do the trick you can try the same with the # key & the 6 key on the printer. This is a semi full reset.

If u still get the error msg its a hardware issue with the printer & cannot be fixed with regular troubleshooting.

At that point unless the printer is under warranty I would replace it because parts aren't available for it.

Envision EN7410e monitor


Just fixed mine. Maybe it's a few years late. Hope you guys still have the display. It's the power supply board. I've just replaced 4 bulge capacitors near one edge of the PS. They are 2x1000uF 10V, 1x470uF 25V & 1x470 10V. I salvaged my parts from an old CRT monitor. Hey you can go green with your repairs too!
