paul_brenner1 Posted August 18, 2004 Share Posted August 18, 2004 Our printer for general use is the HP 6122. It actually does a very nice job on small black-and-white prints, particularly using HP Premium Plus Matte paper. Lately I've noticed that the prints are slightly, but noticeably, lighter. (Same images, same settings.) The black and white cartridge is 75% full, and I've cleaned (but not primed) the nozzles. The cleaning test print indicates no problem. (Although the difference in tone is slight enough that test probably would not show the difference.) After working online with the HP tech rep, my conclusion is that the only thing it can be is paper variation. Does anyone have any different thoughts?

constance_cook Posted August 18, 2004 Share Posted August 18, 2004 Hi Paul. I have a 6122 and I've found that when the humidity is high and the paper absorbs some of this moisture, I get a lighter black than I do under less humid conditions.

paul_brenner1 Posted August 18, 2004 Author Share Posted August 18, 2004 Conni, Thank you! Given where I live, I would think that it would be less humid now then when I was making the prints before (Winter), but you've pointed out how "small" changes like climate etc. can affect the paper. I'm sure that this is the culprit (or part of it.) Paul Link to comment Share on other sites More sharing options...
paul_brenner1 Posted August 19, 2004 Author Share Posted August 19, 2004 Further findings - I printed a color image on glossy paper. The original print was only from late June. This one appears slightly washed-out and veiled vis-a-vis the print from only two months ago. Given that this is different paper, and the comparison print is also from this summer (same climate), I'm back to thinking it's the printer. The one step I haven't taken is to "prime" the nozzles. The warning says it takes a lot of (expensive) ink, and the standard test pages look fine. Can anyone explain what "priming" is and whether it might be likely to address the problem? Any other thoughts? Thanks, Paul Link to comment Share on other sites More sharing options...
constance_cook Posted August 19, 2004 Share Posted August 19, 2004 Hi Paul: Do you have a new set of cartridges you could put in and try? Then you could see if there is a difference between the current cartridges and the new ones. That way you wouldn't waste ink. Conni Link to comment Share on other sites More sharing options...
paul_brenner1 Posted August 19, 2004 Author Share Posted August 19, 2004 Conni, Good thought. Do you know if HP's ink measurement system works such that substituting cartridges screws up the indicators? Paul Link to comment Share on other sites More sharing options...
constance_cook Posted August 20, 2004 Share Posted August 20, 2004 Paul: The new cartridges will register as new/full. When you take them back out and reinsert the old cartridges, it will show whatever is left in them. Conni Link to comment Share on other sites More sharing options...
paul_brenner1 Posted August 20, 2004 Author Share Posted August 20, 2004 Thanks! I believe Epson doesn't work that way. Glad HP does. Paul Link to comment Share on other sites More sharing options...
