## Product: Sharp UXB20 Fax Machine
**Brand:** Sharp

## Pros
- The Sharp UXB20 excels in basic fax functionality, offering reliable performance for sending and receiving faxes with good inkjet-quality output.
- It is easy to set up and use, making it especially suitable for users who prefer straightforward operation or have limited tech experience.
- The compact design helps save desk space, which is a plus for small office or home office environments.
- Uses standard ink cartridges instead of thermal rolls, which some users find preferable.
- Functions well as a replacement for older fax machines or for those avoiding subscription-based broadband fax services.
- Highly recommended for occasional faxing needs rather than heavy or frequent office use.
- Good overall build quality with a quick setup process.
- Works reliably with a dedicated fax line, avoiding internet phone service issues.

## Cons
- The Sharp UXB20 does not perform reliably when used with digital internet phone services (VoIP), with tech support confirming inconsistent operation under these conditions.
- Ink cartridges tend to run out quickly, making ink replacement frequent and costly, especially for more than minimal usage.
- Paper feeding is problematic; it does not handle multiple sheets well and often requires manual feeding, which is inefficient and time-consuming.
- A feedback report prints after each fax automatically, and there is no easy way to disable or cancel this function, resulting in extra paper use and annoyance.
- The fax machine cannot be set to answer immediately and requires at least two rings before picking up, which might be inconvenient.
- Some users reported early malfunctions, such as failure to intake paper properly, leading to inconsistent performance.
- The machine is not suitable for heavy-duty or frequent faxing and may be frustrating for users needing more advanced features or efficiency.

## Bottom Line

The Sharp UXB20 Inkjet Fax Machine is a solid choice if you need a simple, easy-to-use fax device for occasional use, especially on a dedicated fax line. However, its limitations with VoIP phone services, frequent ink cartridge replacements, and paper handling quirks make it less than ideal for heavier office or internet-based faxing needs. If you require more robust performance or better compatibility with digital phone systems, you may want to consider alternatives or broadband fax services that better suit those environments.

If your priority is straightforward faxing without bells and whistles, the UXB20 fits well—but keep the ink and paper quirks in mind before committing.
