Hear, hear, and then bitching about my Brother printer ... :-)Did you check the area where they are parked? Sometimes that develops an impressive deposit of crud.-- Regards, Joerg"gmail" domain blocked because of excessive spam.Use another domain or send PM.

He said not tobother bringing it over, just change the printheads... it _is_ so oldI can't remember when I bought it ;-)                                        ...Jim Thompson-- | James E.Thompson, P.E.                           |    mens     || Analog Innovations, Inc.                         |     et      || Analog/Mixed-Signal ASIC's and Discrete Systems  |    manus    || Phoenix, Arizona  85048    Skype: Contacts Only  |             || Voice:(480)460-2350  Fax: Available upon request |  Brass Rat  || E-mail Icon at  |    1962     |              I love to cook with wine     Sometimes I even put it in the food

Jim Thompson Inscribed thus:Check very carefully under the print head carriage !  You get a buildupof debris directly under the carriage.  Set the printer so that you canremove the cartridges.  Turn off the power so the machine doesn't tryto move the carriage. Use a folded kitchen wipe (Non Fluffy) and insertit under the print head carriage.  Then move the carriage back andforth a few times so that you are wiping it.  You may have to use someisopropyl on the wipe to get it all off.That should sort it for a long while.  In my experience its worse withcheaper paper that produces more dust.HTH -- Best Regards:                        Baron.
