The "Download Standby" error on a Canon iR2016 indicates that the copier's system software (firmware) has become corrupted or lost, leaving the machine in a permanent waiting state for a new software upload. The Cause
This state typically occurs after a failed firmware update, a power surge during operation, or a failure of the main controller's flash memory. When the machine is turned on, it cannot find the necessary instructions to boot the user interface, so it defaults to a low-level "standby" mode intended for service technicians. The Resolution (The "Story")
Fixing this requires specialized service tools that are generally not available to the public:
Service Support Tool (SST): Technicians use a specific piece of software called the Canon Service Support Tool (often version 3.22E or newer for this era of machine).
Firmware Files: The specific firmware for the iR2016/2016J/2020 series is required. Note that while the models are similar, using the wrong firmware (e.g., loading iR2020 firmware onto a 2016J) can lead to language or feature mismatches, though it may "revive" the hardware.
Connection: The machine is connected to a PC via USB. In "Download Standby" mode, the PC may recognize it as a generic device (e.g., "CYFSA") requiring specific drivers included with the SST. Flashing Process: The technician registers the firmware within the SST.
They connect to the machine and first flash the Boot ROM (often version 14.03).
Following a successful boot flash, the System software is uploaded.
If the upload fails with a "Rom write error," it often indicates a physical hardware failure of the memory chips on the main controller board. Verification
The error is considered "verified" and resolved once the SST reports a successful transfer and the machine is rebooted. If successful, the standard "Ready" screen or "Load Paper" prompt will reappear instead of the "Download Standby" text.
The "Download Standby" error on a Canon iR2016 is a critical state where the device's control system is waiting for a firmware upload to function. This typically occurs when the firmware has become corrupted, the Boot ROM is faulty, or a previous update attempt was interrupted. Common Causes of "Download Standby" canon ir2016 download standby error verified
Firmware Corruption: Often caused by power surges or improper shutdowns during a data write process.
Stalled Print Jobs: In some cases, a large or corrupted print job stuck in the memory buffer can trigger a standby loop.
Faulty Hardware: A failing Boot ROM or main logic board can force the machine into this mode because it cannot load the basic operating system. Verified Solutions to Resolve the Error 1. Perform a Hard Reset
Before attempting complex software fixes, try a deep power cycle to clear the internal memory buffer. Power off the machine and unplug it from the wall.
Wait at least 5–10 minutes to ensure all residual charge is gone. Plug it back in and restart. 2. Clear All Settings (Maintenance Mode)
If the machine allows input, you can try a factory reset via the service menu to clear corrupt configuration data. Press the Additional Function key.
Press the 2 key, then the 8 key, then Additional Function again. Use the arrow keys to find #CLEAR and press OK.
Select ALL and press OK. The machine will cycle and reset to factory defaults. 3. Reflash Firmware (Service Technician Level)
If the error persists after a reset, you must re-install the system software using the Canon Service Support Tool (SST).
Requirement: You need a PC with the SST software installed and the specific firmware files for the iR2016. The "Download Standby" error on a Canon iR2016
Connection: Connect the PC to the printer via USB. The device may be detected as "CanonCSFYSA" or "CYFSA"; note that specific drivers for these modes are typically included within the SST environment rather than standard Windows drivers.
Process: Open SST, register the firmware, and use the "System Software Download" option to push the new firmware to the printer. Prevention and Maintenance
To prevent recurring firmware errors, it is highly recommended to use a surge protector or UPS, as power fluctuations are a primary cause of ROM corruption. Regularly clearing the print queue on connected PCs can also prevent memory buffer freezes.

If the basic reset doesn't work, the machine may require a more formal "Error Clear" through its service data: Clear Error Codes : Access the service menu (typically by pressing the Additional Functions simultaneously, then Additional Functions again) and navigate to Clear > Error to reset the internal state. Firmware Re-flash
: If the printer is stuck permanently, the "Boot PROM" (firmware chip) may be corrupted. This usually requires a technician to re-flash the firmware using specialized Canon service tools Inspect for Hardware Faults
: Ensure there are no active paper jams (Error E354) or sensor issues, as these can sometimes prevent the printer from exiting specialized modes. JustAnswer to enter the Service Mode for this model?
Canon ImageCLASS MF6590: Resolving 'Downloading Standby' Issue
Unlike common errors such as "Paper Jam" or "Toner Low," the "Download Standby Error Verified" message is not a mechanical failure. It is a firmware or communication state error.
In simple terms: The copier is trapped between its normal operating system and a failed update process. It believes it is about to receive new software, but the connection never materializes or is invalid.
The Canon iR2016 is a 2005-era device. While rugged, finding parts and parallel-port computers is difficult. If the DC controller board is dead, replacement cost ($100-$200 used) may exceed the value of the device. Consider upgrading to a modern Canon imageRUNNER (e.g., 1643i or 2204) if you cannot resolve the error.
