    Pixma printer doesn't print black. Monochrome laser stupid buy?

    Woah! Yeah, that's a little different. You mentioned photo and pigment inks. By this, do you mean the two types of black ink that are used in the printer? So I should fill one with PGBK ink, and the other from the ink used for the BCI-7BK cartridge? I use ink from Sanwa Supply, sorry to...

    Pixma printer doesn't print black. Monochrome laser stupid buy?

    Thanks all for the input. Here's my test print ... I don't know what the flip is going on! The last time I did a test print, the top half of the PGBK row was simply blank. Now it's back on. I guess I won't complain. Black ink density is terrible. After refilling the same cartridge for...

    Pixma printer doesn't print black. Monochrome laser stupid buy?

    Thanks for the idea, I'll try that. If I use the 'fine' setting, the head passes twice as often and I can get full coverage. However, even with all the settings on the darkest possible, my PGBK only comes out as grey. I bought a brand new OEM cartridge to try to fix it, but the same problem...

    Pixma printer doesn't print black. Monochrome laser stupid buy?

    So my MP610's PGBK head seems to be half fried. I can still get by on the color tanks, and can print composite black by changing text to 'near' black in most applications. I do a lot of B&W printing for ads and handouts, and appreciate good black quality, which I definitely have not gotten...

    Yes, I did an alignment and the problem didn't get solved. Thanks for the input.

    MP610 suddenly stopped printing on return stroke

    Vent sealing tape? Well, I unwrapped it as specified for installation into the printer... There is the 'Push' button, but it doesn't actually seem meant for pushing.

    MP610 suddenly stopped printing on return stroke

    Yes, it seems to fit the description of a bad printhead. However, I only used OEM cartridges! I refilled my original one for years, and only bought my 2nd one when the 'empty when full' problem appeared recently. If I were to throw in my real cheap two cents, I'd say that the false empty...

    MP610 suddenly stopped printing on return stroke

    Thanks much for all the good information. I found the timing belt and inspected it with a flashlight. There are two marks about 2 mm long, and about three marks less than 1 mm long on the belt. I touched them with a qtip but they did not change in character. Other than those marks, the belt...

    MP610 suddenly stopped printing on return stroke

    Is it possible that the print head is fine but the timing strips are dirty? If so, where can I find the timing strips to clean them? Off to search the forums...

    MP610 suddenly stopped printing on return stroke

    PeterB, thanks for the input. I did try to search the forums for a similar problem but didn't find that entry! The last time I took it out was quite a while ago, so I don't think that's it. I live in Japan, so I'm not sure that shipping a print head overseas would be worth it. Unfortunately...

    MP610 suddenly stopped printing on return stroke

    barfl2, thanks for the reply. I had done a head cleaning and a test print, and I just noticed this: The PGBK row of the test print is half missing! The top half is just blank white page; the bottom half that appears is printed just fine, so it's not a clogged head, but the problem I'm...

    MP610 suddenly stopped printing on return stroke

    My Pixma MP610 suddenly stopped printing while the print head is moving in one direction. The result is a page of 1-inch printing, 1-inch blank, repeat until bottom. I have refilled my own ink tanks since purchasing the printer in 2006, and have had no problems until recently. I just refilled...
