Frequently Asked Questions
Which of these numbers is the toner cartridge and which are other supplies?
The 310-7945 and 310-7943 numbers plus PF658 and PF656 cover this printer's toner cartridges in standard and high-capacity versions, while RF223 and NF485 are alternate part numbers for the same family. Match the number on your current cartridge; do not order by printer model name alone, since similar Dell models use different supplies.
My prints have faded bands across the middle of the page, what is wrong?
Faded bands across the middle usually mean the cartridge is running low and toner is no longer feeding evenly, so remove it and rock it gently side to side, which often buys another hundred pages. If the bands return quickly after redistributing, the cartridge is genuinely empty and needs replacing.
Can I leave the printer off for months without harming the cartridge?
Yes, but print a test page when you power back on: toner settles during long idle periods and the first pages may look light until it redistributes. If the printer sat in a hot garage or damp basement, inspect the cartridge for clumping before relying on it for important documents.
