Questions about this item

How do I install these cartridges in my Dell 1250C printer?

Open the front cover, pull each old cartridge straight out, remove the orange protective tape from the new Laser Tek Services cartridge, shake gently side-to-side, then slide it firmly into the matching colour slot until it clicks.

What maintenance will these toner cartridges need later?

No maintenance is required; each black cartridge yields about 2000 pages and each colour cartridge about 1400 pages, so simply replace the empty cartridge when print quality fades.

What limit appears first during long print runs with these cartridges?

The rated page yield is reached first — roughly 2000 pages for black and 1400 pages per colour cartridge — after which a new cartridge is needed.
