RISO Printer Cartridges and Maintenance Guide
Your Complete Handbook for RISO ComColor Printers — From First Purchase to Daily Maintenance
Whether you're deciding which ComColor model fits your print volume, setting up a machine for the first time, or figuring out why your riso ink cartridge isn't being recognised — this hub covers every stage. I've pulled together the most common questions from distributors, print shop operators, and IT managers into one place, so you don't have to piece it together from scattered support pages.
Choosing the Right RISO ComColor Printer for Your Print Volume
RISO printing uses high-speed inkjet technology that runs significantly faster and cheaper per page than laser alternatives for high-volume environments. The ComColor line — sometimes called a riso printing press in commercial settings — spans six series, each optimised for different output volumes, paper sizes, and color requirements. Choosing the wrong series means either overpaying for capacity you don't need, or hitting throughput limits within six months.
| Series | Models | Speed (ppm) | Colors | Best for |
|---|---|---|---|---|
| GL | GL9730 / GL7430 | up to 160 | BK · C · M · Y · Gray | High-volume commercial, 5-color output |
| GD | GD9630 / GD9631 / GD7330 | up to 150 | BK · C · M · Y · Gray | Print shops, direct mail, education |
| FT | FT5430 / FT2430 / FT1430 | up to 120 | BK · C · M · Y | Mid-volume offices, 4-color standard |
| FW | FW5230 / FW5231 / FW1230 | up to 120 | BK · C · M · Y | Compact environments, 4-color |
| X1 | X1 9150 / 7150 / 3150 | up to 150 | BK · C · M · Y | Production print, large format runs |
| CC | CC 9050 / 7050 / 3050 | up to 120 | BK · C · M · Y | Entry commercial, cost-conscious buyers |
Installation & Initial Setup — Network, Scanner & Service Mode
Most RISO ComColor installation problems happen within the first hour: the copy function doesn't appear after connecting the scanner, or the printer can't be found on the network. Neither requires a technician. Both have a clear four-step fix that I've documented from the most common setup calls we receive from new distributors.
How to Use a RISO Printer — Daily Operation Workflow
Knowing how to use a riso printer efficiently comes down to a consistent pre-run checklist. Most production delays I hear about aren't mechanical — they're avoidable: someone started a 20,000-page run without checking ink levels or the waste tank. The workflow below is what high-output print shops run before every large job.
| Before each run | Check | Action if low / issue |
|---|---|---|
| Ink cartridge levels | Home screen ink display | Replace before run starts — mid-run swap causes color shift |
| Waste ink tank | Tank indicator on home screen | Replace if above 80% — full tank stops production |
| Paper feed tray | Paper level indicator | Load full tray — partial loads cause misfeeds on long runs |
| Output tray | Clear and extended | Remove stacked output — overloading causes jams |
| Print head nozzles | Run test page | If streaking: clean nozzles or replace cartridge |
For operators switching from laser to riso printing for the first time: the biggest adjustment is the ink system. Unlike toner, riso inks are oil-based pigment liquids that require the machine to stay in regular use. If the printer sits idle for more than two weeks, run a single color test page to keep the pigment in suspension across all nozzle channels.
RISO Ink Cartridge Selection — Compatible vs OEM, Certifications & Cost
Choosing the right riso ink is the single decision that affects operating cost, print head lifespan, and EU import compliance most directly. The choice between OEM and compatible ink for riso printers isn't just about price per cartridge — it's about whether the ink formulation is certified, whether it will clog the print head after idle periods, and whether the page yield claim is backed by a verifiable test standard.
| Criteria | RISO OEM ink | Quality compatible (Chameleon) | Low-cost compatible |
|---|---|---|---|
| Cost per 1,000 pages | ~$11 | ~$4 | ~$3 excl. repairs |
| MOAH MOSH certified | Yes | Yes — SGS | Rarely |
| Particle size | ≤200nm | ≤200nm | 400nm+ (clogs) |
| Color batch consistency | Guaranteed | QC per batch | Drift reported |
| ISO/IEC 24712 yield test | Yes | Yes — GD7330 tested | No |
Ink for riso machines is not interchangeable across series. Each uses a specific part number — using the wrong cartridge causes recognition errors even if it physically fits. See the compatibility table in the section below for full part numbers by series.

Installing RISO Ink Cartridges — Series Compatibility & Step-by-Step
Replacing riso printer ink cartridges takes under five minutes once you know the sequence. The process is identical across GL, GD, FT, FW, X1, and CC series — the only difference is the release mechanism. Below is the full compatibility list and the installation steps.
Waste Ink Tank — When to Replace, How to Install & Remove
The waste ink tank collects excess pigment ink from print head cleaning cycles. It is the most frequently overlooked maintenance item — and a full tank stops production immediately. For print shops running 10,000+ pages per day, expect to replace the tank every 2–4 weeks. Always keep a spare on hand.
Routine Cleaning & Maintenance — BP Belt, Rollers & Output Tray
Most RISO ComColor mechanical issues are preventable. The machines that stay in production longest are the ones on a consistent monthly cleaning schedule. I've seen print shops lose entire production days to a jammed BP belt or a blocked paper pressing roller — both preventable with a 15-minute monthly routine.
| Component | Frequency | What to do | Guide |
|---|---|---|---|
| BP Belt | Monthly | Wipe with lint-free cloth, check for wear and tension | Cleaning guide · Replacement |
| Paper pressing roller | Monthly | Clean with damp lint-free cloth, remove paper dust buildup | Cleaning guide |
| Output tray | As needed | Remove and inspect for debris, clean guide rails | GD removal guide |
| Print head nozzles | Monthly (idle machines) | Run one color test page to keep pigment in suspension | — |
| KG Roller | Every 3 months | Disassemble and clean with approved solvent | Disassembly guide |
| Pickup roller & pad | Every 3 months | Inspect for wear, replace if paper misfeeds increase | Removal guide |
Printer Repair, Error Codes & Deep Troubleshooting
When routine maintenance isn't enough, RISO ComColor machines give you clear signals through error codes and print quality changes. Most printer repair service calls for ComColor machines involve three issues: paper transport errors, CIS unit failures, and recurring error codes that reset services can't clear. All three have documented fixes that don't require sending the machine out.
Summary: What This Guide Covers and Your Next Step
RISO printing at the ComColor level is a reliable, high-throughput system when set up and maintained correctly. The most common issues — print head clogging, recognition errors, network connection failures, and recurring error codes — all have documented fixes that don't require outside printer repair service.
For riso ink, the decision that matters most is particle size. Oil-based pigment ink formulated at ≤200nm prevents the nozzle sedimentation that sends machines to repair unnecessarily. The cost difference between certified compatible riso inks and OEM is approximately 64% per page — at 10,000 pages per day, that adds up quickly.
If you're sourcing riso ink suppliers, verify three things before committing to any volume: the SGS MOAH MOSH report number, ISO/IEC 24712 yield test data with the machine model specified, and batch samples from two different production runs. Those three checks eliminate most of the sourcing risk.
