I just replaced the toner cartridge for the first time in my HP LaserJet (a Canon CX engine). With the new cartridge, printing is much lighter than before, even with the print density dial turned all the way up. The black areas seem to be about the same shade, but they are smaller! Character strokes are thinner... the problem is particularly obvious with Computer Modern fonts, for some reason. Anybody seen this before? Can I do anything about it short of replacing the new cartridge? What are the odds that that will help? -- tom lane Internet: tgl@zog.cs.cmu.edu UUCP: <your favorite internet/arpanet gateway>!zog.cs.cmu.edu!tgl BITNET: tgl%zog.cs.cmu.edu@cmuccvma

This is quite common. We have had our LJ+ for a few years and replaced maybe 15 ccartridges. You always get thinner (and in my opinion better-looking) lines the first 100 pages or so.

When we change cartridges, the lines get finer etc. Over a period of time (as the cartridge ages), the lines seem to get wider (I think that what you are seeing is normal print quality and it "degrades" to wider at the end of the cartridge life). See if you can find something which was printed back when the machine was new and see if the lines are not finer than what they were just before you replaced the cartridge. -- Mikey (yes "he likes it!") ============================================== Mike Fields ssc-vax!shuksan!mikey (206) 251-4638 [work] 12022 NE 138th Pl.

This is odd, because the LJ+ I work with in one place I consult at doesn't produce good type until after about 20 or 30 copies with a new cartridge. The type is passible, but not the highest quality that one can get out of the LJ+. Is this just our machine, or does it vary that much? Glenn I.

I know it looks funny to stand there and turn the cartridge back and forth several times, but it gets the job done! -- George W.
