One of the most widespread faults encountered by owners of Canon continuous ink system (G-series MegaTank) and cartridge-based Pixma printers after sustained use is Support Code: 5B00 (or in related model revisions, 5B01, 5B02). When this error code strikes, all active printing, photocopying, and scanning jobs halt abruptly, and the entire device locks up completely.
Users experiencing this error often panic, assuming their printer has suffered catastrophic failure. However, in reality, error 5B00 is an engineered preventive safety lockout. It indicates that the absorbent sponge felt pads resting at the bottom of the printer chassis are saturated with purged ink, and the machine has entered lockdown to stop ink from leaking onto your workspace.
In this guide, backed by years of hands-on experience at ProTech Bilgisayar in Antalya, we explain what error 5B00 represents, how to recognize its symptoms, safe home checks, and our permanent workshop solution.
What Is Error 5B00?
Every time an inkjet printer executes a printhead cleaning, deep cleaning routine, or initial ink priming during first setup, it purges a measured volume of ink through its nozzles to keep the microscopic channels clear. This expelled waste ink is directed through silicone tubes into dense, highly absorbent felt waste ink pads (absorber pads) housed in the bottom cavity of the printer.
An electronic waste ink counter stored inside the EEPROM chip on the motherboard tracks every purge cycle and printed sheet mathematically. When this cumulative calculation reaches its 100% threshold (typically between 10,000 and 15,000 pages, or earlier if frequent deep cleaning cycles were triggered), software firmware locks the device and triggers Support Code: 5B00.
Two Primary Dimensions of Error 5B00:
- Digital EEPROM Counter: The mathematical tally on the logic board must be reset back to zero.
- Physical Felt Absorber Pads: The physical sponge pads must be inspected and replaced. Performing a software reset without replacing saturated pads guarantees that liquid ink will soon overflow the base, staining desks and corroding electronic chassis components.
What Are the Symptoms?
Error 5B00 manifests through several distinct indicators:
1. Screen Messages and Error Screens
- Printers equipped with an LCD display show “Support Code: 5B00.”
- On your computer, printing a document triggers a Canon Status Monitor popup: “Printer error has occurred” or “The ink absorber is almost full / ink absorber is full. Contact service center.”
2. Panel Blinking Pattern
- The orange (Alarm) and green (Power) lights on the front panel blink alternately 7 times, followed by a steady green pause, repeating in an endless loop. In Canon official service literature, “7 blinks” definitively identifies the waste ink absorber lockout.
3. Complete Function Lockout
- The machine ignores all control inputs. The internal carriage assembly does not initialize, and even the flatbed document scanner remains disabled.
Which Models Are Affected?
While this mechanism exists across all Canon inkjet printers, it surfaces most frequently on heavy-duty continuous ink supply models:
1. Canon Pixma G Series (MegaTank Models)
- G1400, G2400, G3400, G4400 (First-generation tank units)
- G1410, G1411, G2410, G2411, G3410, G3411, G3415, G4411 (Second-generation, high-volume units)
- G5040, G6040, G7040 (Duplex network-enabled units)
2. Canon Pixma TS and MG Series (Cartridge-Based Models)
- MG2450, MG2550, MG2555S, MG3050, MG3550, MG3650, MG4250, MG5750
- TS3150, TS3350, TS5150, TS5350, TS6350, TS8350
What Can Users Do on Their Own?
Because 5B00 is rooted in low-level firmware safety lockouts, standard tricks (power cycling, unplugging AC cords) will never clear it. However, you can verify your printer’s motherboard state before visiting a repair center:
1. Attempting Service Mode Entry
To communicate with service diagnostic software, the printer must first enter its native “Service Mode”:
- Power off the printer.
- Press and hold the Stop (Red Triangle) button.
- While holding Stop, press and hold the Power button.
- While still holding Power, release Stop, then press Stop 5 times consecutively (on certain models, 6 times). The status LEDs alternate colors with each button press.
- After the final press, release both buttons simultaneously. The green power LED will blink and eventually stay lit solid. A steady green light confirms successful Service Mode entry.
- If your printer successfully enters Service Mode, your motherboard firmware is unlocked and software reset is viable.
2. Beware of Free Online Resetter Programs!
Freely circulated online utilities named “Canon Service Tool v4905” or “v5103” frequently harbor trojans or corrupt code. Running an incompatible Service Tool revision will permanently corrupt the motherboard EEPROM (EEPROM Lock / Brick). Once locked, the machine will never enter Service Mode again, requiring the mainboard to be desoldered and reprogrammed via an external hardware programmer.
When Is Technical Service Required?
Contact ProTech Bilgisayar immediately if:
- The printer refuses to enter Service Mode, or displays erratic LED flashing sequences (indicating board firmware corruption).
- The device enters Service Mode, but reset utilities return “Error Code: 006” or “005”.
- You notice dark liquid ink pooling underneath the printer base (saturated absorber pads).
- The printer has seen heavy daily duty for 2–3 years without any pad overhaul.
What Is the Permanent Solution?
At ProTech Bilgisayar, our comprehensive workshop procedure tackles both halves of the problem:
Step 1: Physical Replacement of Waste Ink Absorber Pads
The chassis casing is completely disassembled, and the saturated, sludge-laden sponge pads are carefully extracted. The internal purge channels and tray are sanitized, and a brand-new set of high-density absorbent felts is installed.
Step 2: EEPROM Counter Reset
Using authorized Canon diagnostic software, the waste ink counter (parameter D) is digitally reset to 0%. If the EEPROM chip was previously locked by a faulty utility, the logic board is extracted, the surface-mount EEPROM IC is desoldered, flashed with factory ROM binaries via a dedicated hardware programmer (such as CH341A), and resoldered.
Service Options and Comparison:
| Procedure Type | Action Performed | Success Rate | Leakage Risk |
|---|---|---|---|
| Software Reset Only | Clearing counter via software | 100% (Temporary) | High (Pads remain saturated) |
| Standard Service Package | Pad replacement + Counter reset | 100% (Permanent) | Zero (Fully guaranteed) |
| Hardware Chip Flashing | Motherboard EEPROM desolder/reflash | 100% (For bricked boards) | Zero |
