How to choose the right ink cartridge for Brother FAX-1840C

If you’re unsure which ink for Brother FAX-1840C to buy, we recommend a simple checklist:

• Match the cartridge symbol: for this model, look for LC-900 series (including LC900BK, LC900C, LC900M, LC900Y) and higher-capacity black LC900HYBK.
• Choose capacity wisely: if black prints disappear fastest in your office, consider XL BK or a BP4 4xpack.
• Pick a set if you want convenience: CMYK multi-packs reduce the risk of running out of one color at the wrong time.
• Add cleaning fluid if needed: if you see streaks, missing lines, or faded colors, a cleaning solution can help restore proper ink flow.

Common Brother FAX-1840C printing issues and what usually helps

Many customers come to us after experiencing problems that are typical for inkjet devices used irregularly. Here’s what we most often see with the Brother FAX-1840C and what to do:

• Streaks or missing colors – often caused by partially clogged nozzles. Run the printer’s cleaning cycle; if the issue persists, consider Fluids for Cleaning and print a test page regularly.
• Faded black text – check if the black cartridge is low; if you print a lot, switching to LC-900 XL BK can reduce interruptions.
• Color imbalance – replace only the depleted color (C/M/Y) rather than the whole set, or choose a CMYK pack for a fresh, even start.
• Infrequent use – ink can dry faster. We recommend printing a small page (even a simple color chart) every 1–2 weeks.
