I have an HP4500 and it is producing faint black vertical lines on the left side of the paper about 1cm wide. I have looked at the imaging drum and it is covered with a fine black film where the lines are. I was thinking of cleaning the drum with a cloth, but I'm not sure. Can anyone offer any advice please. Many thanks John Perry

The drums are good for about 1 1/2 black toner cartridges. If the drum has some miles on then it's worth experimenting with. I used one of the white cleanup cloths that come with the toner cartridges dipped in a little bit of isopropyl alcohol to clean a drum one time. It seemed to work. Used it repeatedly on a transfer belt and got about 3x normal life! -- Chas. verktyg@aol.spamski.com (Drop spamski to E-mail me) "John Perry" <JohnPerry@redoak.co.ukNOSPAM> wrote in message news:lbfs7v8d6p6fvrd495e0s5loqal10ecud2@4ax.com... > I have an HP4500 and it is producing faint black vertical lines on the > left side of the paper about 1cm wide. > > I have looked at the imaging drum and it is covered with a fine black > film where the lines are. > > I was thinking of cleaning the drum with a cloth, but I'm not sure. > > Can anyone offer any advice please. > > Many thanks > > John Perry

Not a lot you can do bar scrap it and start again! Cheers -- Clive Coleman

Not a lot you > can do bar scrap it and start again! This is a common cause I've found, cleaning the drum doesn't do any good as it doesn't tackle the cause. Of course if the drum itself is actually worn then nothing will help. Do you mean scrap the cartridge or the scaper? You can (I've found) actually replace a worn blade. It's a bit of a messy job though. You buy a spare blade from a drum remanufacturer wholesaler, in the early days laser drums were apparently built to survive, so a remanufacturer could often just replace the toner and the blade, later on drums, and associated parts were designed down to last not more than the length of the toner. But first I'd check the corona wires. You should clean them with any sort of volatile solvent. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

It is but a minute or so in low light shouldn't hurt it very much. -- Chas. verktyg@aol.spamski.com (Drop spamski to E-mail me) "John Perry" <JohnPerry@redoak.co.ukNOSPAM> wrote in message news:6b548vg91d4tclr10nifpvggjjmnvqu86s@4ax.com... > "* * Chas" <verktyg@aol.spamski.com (remove spamski to e-mail me)> > wrote: > > >The drums are good for about 1 1/2 black toner cartridges. > >If the drum has some miles on then it's worth experimenting > >with.
