Exam 220-1001 topic 1 question 100 discussion

A. Replace the toner cartridges B. Replace the fuser module

B and D is correct answer. The fuser unit in a copier is responsible for fixing toner onto the paper through heat. If the fuser is not functioning correctly after the maintenance kit installation, it could cause poor color density. Replacing it might address the issue.

According to the official CompTia songbook, regarding troubleshooting faint images on laser printers, "if a simple cause such as the user choosing an option for low density (draft output) can be discounted, this is most likely to indicate that the toner cartridge needs replacing." Furthermore, the aforementioned holy text also says that a "maintenance kit" for one of these printers includes a set of replacement feed rollers, new transfer roller, and a new fuser unit." - in my experience, a maintenance kit (for a copier) would include a shiny new (empty) waste toner catch can, and that "emptying" your old catch can is expressly forbidden. One last thing: The process for replacing the components in a maintenance kit (according to the Good Book) also includes resetting page counts to zero.

Found on the other site A and C as answers, can somebody verify please.
