Panasonic KX-FLM653RU Review: Features, Specs, Performance

By -

Overview & positioning

The Panasonic KX-FLM653RU is a mono (black‐&‐white) multifunction device combining fax, print, copy and scan functions. According to the user manual listing, it is a “Multi-Function Laser Fax” machine.
It is targeted at small offices or departments that require integrated fax + printing + scanning, not a full colour multifunction office copier or network production device.

Because it’s an older device (circa mid‐2000s), it likely offers modest speed and modern features compared to current MFPs, but may still be useful in specific use-cases.

Key features & specifications

From the manual/spec listings:

  • Printing Technology: Mono laser (or at least mono laser‐fax combo) for A4 size.

  • Print speed: ~ 14 pages per minute (mono-A4) according to one spec sheet.

  • Print resolution: 600 × 600 dpi for printing.

  • Scanner: Supporting scan size up to 216 × 297 mm (i.e., A4) with resolution 600 × 600 dpi, improved up to 9600 × 9600 dpi (software interpolation) in some spec lists.

  • Fax: Super G3 speed 33.6 kbps for sending/receiving faxes.

  • Memory and interface: USB 2.0 interface for PC connection; fax memory 170 pages in one specification.

  • Paper handling: Standard paper tray ~250 sheets (in one spec sheet) for printing.

  • Consumables: Uses a toner cartridge (Panasonic part KX-FA83A in one listing) with yield ~2,500 pages in one spec.

So in summary: mono print/copy/fax/scan; modest speed; A4 format; basic connectivity; targeted for small office use with integrated fax.

Performance & real-world suitability

Print & copy

With ~14 ppm print speed (mono) at 600 dpi, the KX-FLM653RU would manage typical office document tasks (letters, forms, internal reports). It won’t match modern high-speed lasers, but it’s sufficient for less intensive use.
Copy functionality is built-in (as part of the MFP/fax combo) so for small volumes of copying the device should be functional.

Fax

Given the Super G3 fax capability, automatic dial, caller ID, memory for fax reception—this machine is suited for environments where faxing remains required (legal, health, government offices). The integrated handset or phone interface supports voice calls as well (per some specs).
Because the machine includes both fax and print/scan, it reduces footprint compared to separate devices.

Scanning

The scan resolution and A4 capability is useful for document digitization and archiving on a moderate scale. However, the speeds and features will be basic compared to dedicated scanners or modern MFPs.
Because the model is older, expect slower scan throughput and less advanced network scanning or workflow features.

Business use cases

Where this machine may work well:

  • Small offices or back-office departments with moderate mono print/fax/scan volumes (say <1,000 pages per month)

  • Environments where fax remains important, but colour printing isn’t required

  • Workflows where integrating scanning/fax/printing in one device simplifies infrastructure

  • Cost-sensitive settings where the older machine is acceptable for basic output

Where it may not suit as well:

  • Colour printing or heavy graphic output (this is mono only)

  • High-volume print departments (e.g., >5,000 pages/month) — speed and capacity may be limiting

  • Organisations needing modern networked workflows (cloud print, advanced finishing, mobile print)

  • Environments needing full A3 output, heavy duplex scanning, or advanced finishing (staple/punch)

Strengths & limitations

Strengths

  • Integrated multi-function: print, fax, copy & scan in one device

  • Mono printing with decent resolution (600 dpi) for standard office documents

  • Fax capabilities built-in (Super G3, memory, caller ID)

  • Potential cost savings if the device is functioning and consumables are still available

  • Compact footprint relative to separate devices

Limitations

  • Speed (~14 ppm) is sluggish by modern standards

  • Mono only — no colour output

  • Limited modern connectivity (USB 2.0 likely only, no indication of full network or cloud support)

  • Consumable yield modest (2,500 pages per toner cartridge in one spec) so cost-per-page may not be great today.

  • Older device — parts availability, service, driver support may be problematic

  • No advanced finishing, duplex scanning, or large paper capacities typical of newer MFPs

Deployment & operational considerations

  • Consumables availability: Ensure compatible toner cartridges (e.g., KX-FA83A) and drum units are still in supply locally. Without them, support may be an issue.

  • Support & service: Because this is an older model, check that service technicians, spare parts and drivers (for current OS) are still accessible.

  • Network connectivity: If the device only provides USB 2.0 and lacks Ethernet or WiFi, you’ll need print servers or network adapters — may limit its suitability for multi-user offices.

  • Space & workflow: If faxing and printing are integrated, you save space; just ensure you allocate adequate space and ventilation for this MFP.

  • Print volume matching: Align with your actual print/fax/copy volume — if you exceed recommended duty cycle or require faster throughput, invest in a newer higher-speed device.

  • Energy & efficiency: Older devices tend to consume more standby/wait power and may not include energy-saving modes compared to modern systems — consider this in total cost of ownership.

  • Legacy integration: If your workflow still uses paper faxing and scanning into PC workflows, this unit may integrate well; but if you're moving to digital/cloud workflows, a newer MFP may offer greater long-term value.

Final verdict

The Panasonic KX-FLM653RU is a capable multifunction mono laser/fax/scanner unit suitable for a small office with moderate print/fax needs and a requirement for integrated functions in one device. If your needs are basic, mono and you’re cost-sensitive — this model offers value.

However, given its age and limitations, if your business needs any of the following — colour printing, high volume, modern connectivity, advanced finishing or long-term future-proofing — you should strongly consider investing in a more modern multifunction laser or inkjet system.

Recommendation:

  • Good if you need a budget mono/fax/scan/print solution and the existing device is available at low cost, with consumables support.

  • Pass or upgrade if your workflow requires colour, higher speed, network mobile printing, or you expect to scale print volumes.
