REMANUFACTURING THE HP LASERJET
P1006 SERIES TONER CARTRIDGE CB435A
By Mike Josiah and the Technical Staff at UniNet
In November 2007, Hewlett Packard released the LaserJet P1006 printer. The HP P1006 series of laser printers are based on a
17 ppm, true 600dpi Canon engine. These cartridges use a chip that controls the toner low functions. The CB435A is rated for
1,500 pages. Physically, the cartridges look like a small 12A (1012) cartridge, but there are many differences.
The printer itself has a very small foot print. It's a nice small office/home machine. The first page out is stated to be in under 8.5
seconds from a power save mode. The memory is fixed and not expandable at 8Mb. The recommended monthly volume is from
250-1,500 pages per month, but the maximum monthly duty cycle is 5,000 pages. Unlike many small printers these machines
have an input tray that can hold 150 pages. A nice touch!
The system that holds the two halves of the cartridge together is completely new. The good news here is that you don't have to
cut holes in the cartridge to get access to the pins. The toner inside is also new. HP is stating that the toner now has
"spherically shaped particles". We are currently investigating if this means the toner is chemical or conventional toner that has
been thermally rounded. My guess is that it is thermally rounded toner, but until our investigations are finished, we won't know
In addition to the new toner, the chips have also had "intelligence added" to help aid cartridge ordering when supplies are low.
Again, we are investigating the chips for these cartridges as I write this. I can say I have run the same cartridge now five times,
and the chip has not shut the printer down. Just the toner low features are not working.
The printer when new comes with a starter cartridge that is rated for 700 pages at 5% coverage, so your customers will be
coming to you fairly quickly!
Printers based on this engine so far are the P1000, P1005, P1006, P1007, P1008 and P1505.
