Some components of the Mutoh RJ900 naturally wear out faster than others. Cap tops and dampers are among the most critical parts and should ideally be replaced once a year. Depending on the quality of ink or solvent you use, these parts may clog even sooner. Lower-quality solvents tend to leave residue, leading to faster blockages and reduced suction. These replacement cap tops and dampers are available on our website, and you can easily buy them from House of Parts when it’s time for a change.
Wiper blades and flushing supports wear out even faster. In most cases, they should be replaced every three months, especially if the printer is used daily. When wiper blades start failing, you may notice more frequent nozzle dropouts and increased ink buildup around the printhead. Replacing these parts on time—available on House of Parts—is one of the simplest ways to avoid print defects and machine downtime.
Another important component that requires attention over time is the T Fence A1 Assy DF-49024 for the Mutoh RJ-901C (Drafstation Pro). This original Mutoh part functions as the encoder strip, playing a critical role in accurate printhead positioning and precise media tracking. When the encoder strip becomes dirty or damaged, it can lead to misaligned prints, inconsistent output, or positioning errors that directly affect print quality. Replacing the T Fence A1 Assy helps restore accuracy and ensures smooth, reliable printing performance. This original Mutoh T Fence A1 Assy DF-49024 is available on our website, and you can purchase it directly from House of Parts for dependable maintenance and long-term printer performance.
The Drafstation Pump Cap Assembly DF-49030 is another key part that eventually fails due to regular use. Since it includes the cap top, pump, and wiper, it plays a major role in cleaning cycles. If you use your Mutoh RJ900 frequently, this assembly should be replaced once a year. Light users may get up to two years of use. Reduced suction during cleaning or repeated missing nozzles in test prints are strong signs that this part needs replacement. You can find the Drafstation Pump Cap Assembly directly on the House of Parts website.
Original vs Generic Parts: What’s the Better Choice?
When it comes to replacement parts, many printer owners wonder whether to choose Original or generic options. While generic parts are cheaper upfront, they often wear out faster and can compromise printer performance. Original Mutoh parts are manufactured to exact specifications and go through strict quality checks, which means better durability and more reliable operation.
In the long run, Original parts will save you money in the end since they prove to be longer-lasting and prevent possible damage to other parts. At House of Parts, rest assured that our original parts have been specifically manufactured to suit your Mutoh RJ900 printer.
Keep Your Mutoh RJ900 Replacement Parts Clean
Replacing parts alone isn’t enough—proper cleaning is just as important. Even new components can fail early if ink residue and debris are allowed to build up. You don’t need to clean everything daily, but following a consistent routine makes a big difference.
Wipers and cap tops should be cleaned at least twice a week, while the printhead should be cleaned once a week. Flushing box inserts should be cleaned or replaced twice a month. This simple maintenance routine helps ensure smooth ink flow and protects your investment.
Final Thoughts
Waiting for parts to fail completely often leads to higher repair costs and lost production time. Regular replacement of common Mutoh RJ900 parts, combined with consistent cleaning, can save you hundreds of dollars and extend the life of your printer.
With its excellent print quality, smooth gradients, and fast output, the Mutoh RJ900 is well worth maintaining properly. By sourcing reliable OEM replacement parts from House of Parts, you can keep your printer running efficiently and producing professional-grade results for years to come.
