Frequently Asked Questions

What makes toner not stick to the paper in the ML-1666, and is it dangerous to keep using the printer on plain paper?

When toner sits on the surface instead of melting into the fibers, the fuser — the hot roller at the ML-1666's output — is the prime suspect. If plain paper also smudges with a fresh MLT-D104S installed, the fuser itself is probably failing and needs service or replacement. Match the setting to the paper before suspecting hardware — it fixes most cases.

How do I find the toner gauge for the ML-1666, and what does the low-toner warning look like without opening it up?

The most reliable check is the supplies status page, which the ML-1666 can print from its menu without a computer. When the warning first appears you usually still have a useful number of pages left, so it is a heads-up, not a stop sign. Two seconds of checking beats a stalled print run.

My ML-1666 says toner is low but I need a few more pages — does shaking it actually work without making a mess?

The rocking trick is legitimate: toner settles and clumps as the cartridge empties, and redistributing it restores even flow for a while. Do it over newspaper in case a little toner escapes, and keep the motion slow and gentle to avoid stressing the cartridge seals. A gentle rock now, a fresh cartridge for the ML-1666 soon: that is the right sequence.
