Question about Canon MultiPASS MP730 All-In-One InkJet Printer

4 Answers

Canon MultiPASS MP700

I have tried every maintenance test in the book on my heretofore wonderful MP700. it, however, will print only cyan-heavy stripes in any graphic areas. the print seems to come out fine, regardless of color, tho it is not always accurate in match to that on screen, but this blue-stripe business is driving me crazy. i do a LOT of amateur invitation-type work and use a lot of graphics. on the Print Head Alignment test, Columns L and M choices were striped all the way from -3 to +3, black and dark red alternating. PLEASE HELP ME! DO I NEED A NEW PRINT HEAD? A NEW PRINTER??

    I have the exact same problem. I have had this printer for four years and it's been perfect every step of the way until a week ago. I have contacted Canon directly and am awaiting a response.

    I also have the same problem which has just occurred after 5 years.

    Have replaced the ink cartriges with new, removed and fully claened the print head, realigned several times with no effect.

    I was next going to try a new print head (which knowing Canon probably costs more than a new printer?)

    i, too, have found printheads on line. BUT how hard are they to switch out? surely not as easy as the color cartridges. is there a way i can BREAK it in trying to install it?

  • mqst Apr 07, 2008

    how hard is it to install a new printhead and, if necessary, a new inkpump?

    Same perhaps similar problem, I get a warning that says "WRONG CARTRIDGE" which Canon's website says that the Printhead may be faulty. This error message does NOT allow me to print

I had the same problem. My 4 year old MultiPASS MP700 started banding magenta stripes across everything I printed.
I suspected the cyan printhead was clogged because the printhead tests showed two of the cyan columns as half missing.
Canon was less than helpful. I went off of my suspicion that I needed a new printhead. I found one from an online supplier for 50 bucks...better price than a new printer! I put the new print head in and it works like new.

I replaced the printhead on my MP700, and then found that I needed a new 'inkpump' as well. Verdict? Don't buy Canon.

    Replacing the print head may help, but it may only help for a while, as you could have problems with the 'purge unit', which cleans the print heads, or possibly with the felt soaker pads deep in the chassis of the machine, which could be saturated with old, and now sticky, 'cluggy' ink.


    Once you have dismantled the machine, removal and cleaning of the felt pads is quite do-able, though very messy.Or you could buy new ones as they are only $2 or $3 each. Replacement of the purge unit is also do-able, but unless you are very handy, it might be best to get you service shop to do it. I have not removed a purge unit myself yet, but am about to try.


    Cleaning the print head is quite easy. I have found the best way is to simply pour very hot water onto the top of the ink receptor pads (where the pad on the bottom of each cartridge contacts the print head) until no more ink comes out. Naturally, this is after you take the print head out of the machine. Do not let water contact the metal contacts on the back of the print head. Gently dry the print head by blotting onto paper towel or tissue.

I couldn't print anything black. Bought a new black cartridge, but still nothing in pure black. Removed the printerhead and cleaned off some old dried up ink. Replaced it and everything worked like a charm. Now I have an extra black cartridge that will probably dry up before I get to use it though:-)

Lines on print. There's are three lines on picture print only. Can't see the line on document. It's about 1/4 inch wide and going throught top to bottom.


Have ou gone into your menus. Into troubleshooting, then image quality.
You will want to run both the eliminate light stripes and eliminate smears procedures. that will purge the print head, blow air through the jets and hopefully resolve the problem. I do believe the 8550 has a Jet Substitutin procedure where you can do a workaround and make other jets make up for the light areas.
here are some directions, Will forward more

  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Troubleshooting Print Quality Page], and then press the [OK] button.
  4. Evaluate the 'Light Stripes Test' page for missing printhead jets, such as missing Cyan, Magenta, Yellow or Black color bars. The 'Light Stripes Test' page is the last page of the Troubleshooting Print Quality Page that printed.

    WARNING: To avoid injury, do not touch the sharp metal strip attached to the clear rubber wiper blade in the Maintenance Kit.

  5. Use a clean lint-free cloth or a new paper coffee filter to gently clean the maintenance unit's clear rubber wiper blade, use only a wiping motion across the entire length of the wiper blade, and then empty the waste tray. A dirty maintenance kit wiper blade can cause white lines and weak or missing printhead jets.


  6. 8500-wiper-blade-clean.jpg

  7. Repeat step 3 to reprint the Troubleshooting Print Quality Pages. If there are no missing or partially missing color bars then the print quality problem has been resolved. If there are missing or partially missing color bars then the printhead cleaning procedure will need to be performed. Continue with the next section.
To clean the printhead using the basic eliminate light stripes procedure:
  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Eliminate Light Stripes], and then press the [OK] button.
  4. Press the [Up] or [Down] arrow button to select [Basic], and then press the [OK] button. The printer will perform a head cleaning, which will take about five minutes. The printer will then print a cleaning page and a light stripes test page.
  5. Repeat steps 1 - 4 one more time. If there are no weak or missing jets then the print quality problem has been resolved. If there are still weak or missing jets after two basic light stripe cleanings, continue with step 6.

    NOTE: Do not try the Advanced Eliminate Light Stripes Cleaning mode without performing two basic cleanings first.

    To clean the printhead using the advanced eliminate light stripes procedure:

  6. Press the [Up] or [Down] arrow button to select [Advanced], and then press the [OK] button.
  7. Select the missing jet color and number. If necessary, check the light stripes test page to determine the color and jet number of the missing jet.

    NOTE: Only perform the advanced light stripe cleaning once. If weak or missing jets still persist, continue with step 8.


  8. Print the Troubleshooting Print Quality Page. Evaluate the Light Stripes Test page for missing printhead jets, such as missing Cyan, Magenta, Yellow or Black color bars. If necessary, perform the basic eliminate light stripes procedure one more time. If the Advanced Eliminate Light Stripes procedure does not resolve the weak or missing jets, perform the Enable Jet Substitution Mode. See the Related Items below.

Bad streaking on print xerox 8550 phaser tried the troubleshooting feature/eliminate light stripes with no luck


The best way to tell if your problem is clogged jets, or bad maintenance kit, or something blocking jets. Is to look at light stripes test, and see if missing jets are all in a straight row or all over the place. If the missing jets number less that 10 you can use jet substitution to avoid the streaks. If you are using Media Sciences or some other after market ink, check that most of your problems are not in the cyan area. Media Sciences produced a bad batch of cyan which clogged the jets pretty bad. The good news is that if their ink caused the problem they will pay for some one to come out and replace your printhead. If you LST (Light stripes test) has a smear the entire vertical lenght of the page. You have either a bad maintenance kit, or a piece of paper, lable etc..rubbing against the drum while printing

I have a Xerox Phaser 8400 with image problems. After power up it prints a Startup Page - That page is black text which faded and slightly distorted in some areas and in areas that are in Color only...


What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

Lines appearing across printed photographs


Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

Pages printing blank


Resolving white, light lines or streaks (eliminate light stripes)

From the printer, print the Troubleshooting Print Quality Pages.
With Troubleshooting highlighted, press the OK button.
Scroll to Print Quality Problems by pressing the Up or Down Arrow button. Press OK.

Scroll to Troubleshooting Print Quality Page. Press OK.
Evaluate the Light Stripes Test page for missing printhead jets (missing cyan, magenta, yellow or black color bars).

Clean the maintenance unit's wiper blade and empty the waste tray. A dirty maintenance drawer wiper blade can cause white lines and weak or missing printhead jets. Using a clean lint-free cloth or a paper coffee filter, gently clean the blade with a wiping motion across the entire length of the wiper blade.

Ink in blue slot is not dissolving


If your printer still can print but with no cyan color then you most likely have a bad printhed. If your cyan ink is not melting it's because it is not using any ink . Get into the "print quality" menu and print the test page. If you get black, yellow, and magenta but little or no cyan then your printhead is bad. Whith these machines cyan is the first color to have poblems starting with weak or missing jets.

You can try to run the "eliminate light stripes" to see if it will help.
Run it about 3 to 5 times. If still not working right, turn the printer off for at least 4 hours and then test again.

Hope this helps,
Dan

Xerox Phaser 8500 color issue


In all honesty, I suspect the print head has some bad jets on it.
Xerox will not warrany it since there is the presence of non xerox ink in the print head.
When you have tried as much as you have with the maintenance cycles. I would suspect a bad printhead.
When the jets become blocked to the point where you cant get all the colors sprayed onto the drum, you get mismatched colors.

MP700 Magenta horizontal stripes


I have the same problem. Here's the advice I found somewhere on the internet:

If a jet (nozzle) in your cartridge has gone bad you will see horizontal bands and/or white streaks in your print. Print characteristics may appear incomplete and/or the filled in areas on may not show up.
1) Run some warm water over the print head. This can wash away any ink which might have dried in the cartridge print head. Dry the cartridge with a lint-free cloth before placing back into the printer.

2) Clean the contacts on the cartridge (the copper colored circuitry) and the contacts where the cartridge clips into the printer with water or alcohol. After cleaning, insert and remove the cartridge from the printer a few times to be sure you have a good connection between contacts on the cartridge and the printer.

3) If your print is smeared cleaning the wiper blade may fix the problem. Do this according to your printer manual instructions.
