    The printer is plugged in and there is power in the cord. There seems to be a protection circuit which has kicked in. Does anyone know about this curcuit?

    I have the same trouble and I explain in solution 2

  • Bill T Feb 05, 2008

    zoulou99, Thank you for confirming my problem with the unit. I also took the side panel off and found the fuse. It was intact. I feel a schematic plan would be helpful here. I really feel that the short is in the area of the printer head. I'll let you know once I get that area apart. When you cleaned your printer head, what did you use?

    I have the same trouble, I clean my printer head too. I put in and
    power turn off. I wait a moment and the power came and after the next
    day, nothing. power comand doesn't work. I remove the side behind the
    power cord and I check the continuity of the fuse and it's OK. Somebody
    have a Idea about that. Can I find the schematic plan of the printer to
    search my trouble.

    Hi, I have nearly the same problem with MP750 after I removed, cleaned the inserted the head again. After printout a testpage the printer was blocked. Display didn't light anymore but text was still displayed. After replug the mains cable, switch on the printer was not possible anymore. The display showed only the whole last row black (bar) but was not lighting.
    After a few days I repluged the mains again. The display was lighting, but the printer was in a undefined status. After switch off/on I was able to print out a site but sometimes text display and the light desapears and the printer do the switch on procedure again. May be something is wrong with the switched power supply unit. Have you been able to fix your problem?

Check to make sure the power cord is plugged in all the way in the back of the unit as well as to the wall. Try all the obvious things first. change wall out let you have it plugged into etc. Good luck

    Bill, I just read the users manual completely and the only other thing it list other than those we spoke about is a faulty power cord.. it says and I quote " Either replace the power cord with another, suitably fused, or using a tester, check whether the cord is defective." what jumps out at me is the "fused" part. Could they have an inline fuse in the cord itself. I would get a multimeter and check continuity end to end of the power cord. Sorry thats the best I could come up with out having the printer to work on. Kevin

Replaced black, would not print black, deep clean times two and still the same problem. What can I do?


Hi, the print head needs to be removed and washed with warm water, Please check the manual for print head removal and re-installation. Also print head alignment must be done on re-installation. The process sounds complicating but is quite simple. Do as if you are replacing a ink cartridge. When the print head is at centre in this process and stops.Switch power off on printer.Remove the cartridges, then remove the print head, wash in warm water carefully, do not use any brush or do hard rubbing, dab dry on paper towel. Replace print head into printer, then cartridges, then switch power on. Do print head alignment, clean print head once and print test pattern. Hope this helps as it has worked for me and is still working. All the best.

Blinking/flashing lights(orange & green) & won;t pring. Have rebooted computer and unpluged printer. still won't print.


that is because ur head of ur printing cartridge is damaged.

remove ur cartridges black as well as color
n install only black cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur black cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of black cartridge is damaged
after this process remove the black one cartridge and install the color one cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur color cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of color cartridge is damaged
now take a dry cotton cloth n gently clean ur cartridges head install both cartridges on ur printer n check ur blinking light on ur printer that will work only if u r too lucky other wise u have to purchase a one cartridge.

My Epson C86 Printer is not printing - I've tried cleaning the heads (at least 10 times) but it is still not printing. Is there anything else I can do??????


Hi,

Have you tried the steps below, if not, try them Turn on the printer by pressing the"Power" button. Check the red "Ink" light next to the powerbutton. If it is flashing, you need to first replace an ink cartridge. If the"Ink" light is off, proceed with the cleaning process. 2 Open the Epson Printer Utilityprogram installed on the computer connected to the printer. In the mainmenu, click the "Head Cleaning" option. Click "Start" tobegin the cleaning process. This may take several minutes. You will hear noisesfrom the printer and the "Power" light will begin to flash. 3 Load paper into the tray when the"Power" light stops flashing and you no longer hear noises. Click the"Print Nozzle Check Pattern" option on your screen, then click"Print" on the following screen. The printer will now print a testpage. 4 Click "Finish" if thetest page looks complete. If there are gaps in the image or white lines runningacross the page, the print head needs to be cleaned again. Click the"Clean" option on the final screen instead of "Finish" toclean the heads again. Once again, the printer will print a test page whenfinished. If the page does not meet your standards, clean the head until youare satisfied.

If this does not work, try the steps below.

The fix is described here:
http://inkjetprinterhelp.us/duraink.html

But I had a few problems trying to apply it. I wound up with one of those"extra" parts. (see http://www.fixyourownprinter.com/forums/printer/37654)

So, be advised that the fix is non-trivial to perform if you're a klutz likeme, and also you probably DON'T need to disassemble the print head. (On theother hand, if you DO disassemble the print head, and you see a little partlike the one I found, please tell me where it goes!).

Regards,
Ron

Cannon recommend a cleaning process called deep head cleaning

  1. Open the Printers folder.

    - For Windows XP select 'Start', 'Control Panel', 'Printers and Other Hardware', and 'Printers and Faxes'.
    - For Windows versions other than Windows XP select 'Start', 'Settings', and 'Printers'.

  2. Right-click the printer icon and select 'Properties'.

  3. Click the Maintenance tab, and then click the 'Deep Cleaning' icon.

    win_maint_deep_clean1.jpg


  4. Select the ink tank color(s) for deep cleaning ('All Colors', 'Black', or 'Color').

    win_maint_deep_clean2.jpg


  5. Confirm the message, and then click the 'Execute' button.

  6. The Power lamp will blink and print head deep cleaning will start. Deep cleaning completes when the Power lamp stops blinking and lights. (It will take about a minute for the Power lamp to stop blinking and light solid.)

  7. Print a Nozzle Check Pattern by holding down the <Resume> on the printer until the Power light flashes twice to determine if further cleaning is necessary. Up to three deep cleanings may be necessary to determine if the print head is working properly

Hi altashll,

Printers can be such a headache. Your problem could be one of two things.

Change the Ink
First, your printer may just be low on ink and the cartridge needs replaced.

Clean the Print Head
If you are having the same problems after replacing the cartridge, you may need to clean the Print Head. This is easier than it sounds. All you have to do is press and hold the Stop button for at least 3 seconds until the On light starts flashing. Then release. You will hear the printer making quite a racket, but the cleaning should only last 1 minute (do not turn off your printer during this process or you may damage it permanently)

Good luck.

There is no ink on the paper


Hi Kontiki28. It seems you either have seriously blocked black ink nozzles, or you have faulty black ink nozzles. You can try the nozzle cleaning method described below, but remember it can take quite a while.

Turn the printer on, and as soon as the print head moves out of its parking position, pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head by hand fully into its parking position so that the cup full of fluid comes up over the print head. Do not turn the printer on at any stage in this process. Leave this for at least 24 hours, then turn the printer on and try a head clean/nozzle check again. If you get any black ink on the nozzle check, then there is hope! Repeat the process until you get a full black nozzle check.

If nothing, repeat the process once more. If still nothing, post a new comment detailing what you have done and the results.

Epson Stylus C84-brand new - will not print

When the green light flashes by itself, it means the printer is up to something e.g. doing a head clean. Once you have got the green light steady AND the ink light off AND the paper light off, you are ready to print. If you get nothing on the paper in this situation it simply means the ink is not getting from the cartridges to the paper. Before you go any further, it is ESSENTIAL to be sure you have a good set of ink cartridges. If you are not sure, fit a new set - you can always use the old set in due course when your printer is working properly.

Have you tried a cleaning cycle? If not, try one (right click the little printer icon in the bottom right corner of the screen and select head clean). Now run a nozzle check (right click the little printer icon in the bottom right corner of the screen and select nozzle check). Is there any sign of ink on the paper. Try up to three cleaning cycles. If ink is now flowing, but not yet perfectly, don't carry out any more cleaning cycles. Just leave the printer for 24 hours (to allow any air in the print head to disperse). Then repeat the cleaning cycle/wait process. It may take a while to restore a perfect nozzle check print. If these actions produce no positive results, report back.

If you have already done lots of head cleans with no result, and you're sure you have good ink cartridges properly installed, then You can try soaking the print heads for 24 hours (or more), as follows. Turn the printer on, and as soon as the print head moves out of its parking position, pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head by hand fully into its parking position so that the cup full of fluid comes up over the print head. Do not turn the printer on at any stage in this process. Leave this for at least 24 hours, then turn the printer on and try a head clean/nozzle check again. If nothing, repeat the process once more. If still nothing, post a new comment detailing what you have done and the results.
