About the Epson C11CH81201
The Epson C11CH81201 is a 37 ipm wide-format color inkjet printer certified under the ENERGY STAR program for imaging equipment. The manufacturer markets it as the SC-T5770D.
It uses an inkjet imaging engine and is rated at 37 images per minute (ipm) in monochrome. As a large-format device, it handles wide media such as plans, posters or maps, typically on rolls.
It draws 1.56 W in sleep and 0.08 W when switched off (standby). That sleep power is lower than 35% of the 106 Wide-Format Printer models in our database. The factory default is to enter sleep 15 minutes after the last job.

Safety information
- Plug the printer directly into a grounded wall outlet. Avoid light-duty extension cords, and replace a damaged power cord before use.
- Keep the ventilation openings clear and leave the clearance around the unit that the manual specifies for paper trays, covers and service access.
- Switch off and unplug the unit before cleaning it or reaching deep inside to clear a jam.
- Keep ink cartridges, bottles and waste-ink boxes away from children. If ink contacts skin, wash with soap and water; if it gets in the eyes, rinse with water and seek medical advice if irritation persists.
- Wide-format systems are heavy. Use two or more people, or the lifting equipment specified in the installation guide, and lock floor-standing casters once the unit is in place.
Setup
- Unpack and remove shipping materials
Remove all tape, foam and protective film, including pieces inside the covers and paper trays. Some models also have a printhead or carriage restraint; remove it as shown in the setup guide.
- Choose a location
Place the unit on a sturdy, level surface (or its floor stand) away from direct sunlight, heating vents and humid areas. Leave room to open covers and pull out trays.
- Install ink and printheads
Install the ink cartridges or fill the ink tanks with the bottles supplied, matching each color to its slot. The first start-up runs an ink-charging cycle that can take several minutes; do not turn the printer off during it. Setup ink partly fills the ink system, so the first set yields fewer pages than replacements.
- Load paper
Fan the paper stack, adjust the tray guides to the paper size and load it below the fill line. For roll media, mount the roll on the spindle and feed it until the printer detects it, then enter the media type in the control panel.
- Connect to your computer or network
Connect the unit to your network (Ethernet or Wi-Fi where available) or directly by USB, following the setup guide. Network connection lets several users share it and makes firmware updates easier.
- Install drivers and software
Add the printer in your operating system. Many current network printers work with driverless standards such as AirPrint, Mopria or IPP Everywhere; install the full manufacturer driver if you need finishing, security or accounting features.
- Check the sleep timer
The unit is shipped to enter sleep 15 minutes after the last job. Keep this setting (or shorten it) to minimize idle energy use.
Using your printer
Printing
- Choose grayscale in the print dialog for drafts and text-only pages to save color toner or ink.
- Use draft or standard quality for everyday documents; reserve best or photo quality for photos on matching paper.
- Select the correct paper type and size in the driver so the printer applies the right heat or ink density.
- Print at least once a week to keep the nozzles from drying out.
Sleep and power settings
The factory sleep delay is 15 minutes. In sleep the unit draws 1.56 W, and 0.08 W when switched off at the power button. Turn the printer off with its power button rather than a power strip, so the printhead is capped and does not dry out.
Care and maintenance
| When | What to do |
|---|---|
| Weekly | Print a page (or run a nozzle check) to keep ink flowing. |
| When print shows streaks | Run a nozzle check, then a head cleaning only if needed — cleaning cycles consume ink. Wait several hours between repeated cleanings. |
| When prompted | Replace ink cartridges, refill tanks with genuine bottles of the correct type, and replace the maintenance box (waste-ink pad) when the printer asks. |
| Every 6 months | Install firmware updates from the manufacturer and vacuum dust from the exterior vents. |
Troubleshooting
Most printer problems come from media, consumables, connections or settings. Try these steps first; for numbered error codes, look up the code in the manufacturer's manual or support site.
| Problem | Possible cause | What to try |
|---|---|---|
| Shows offline or jobs stay in the queue | Network or IP address changed; wrong driver or port; printer asleep and not waking. | Restart the printer and computer, print a network configuration page, re-add the printer using its current address, and reserve that address in your router. |
| Streaks, banding or missing colors | Clogged nozzles; printhead misaligned; low ink. | Run a nozzle check and, if needed, a head cleaning; then align the printhead and check ink levels. |
| Cartridge not recognized | Protective tape left on; contacts dirty; incompatible cartridge. | Remove the tape, reseat the cartridge, wipe contacts with a dry lint-free cloth, and use the cartridge type specified for this model. |
| Smudged or wet prints | Paper type setting wrong; printing on the wrong side of photo paper. | Select the correct paper type and load photo paper glossy side toward the printhead as shown on the tray. |
| Paper or media jams | Wrong media for the tray; overfilled tray; worn rollers; debris in the path. | Remove jammed media in the direction of the paper path, check for torn pieces, reload within the fill line, and clean the rollers. |
| Slow to start the first job | Unit waking from sleep. | This is normal. Group jobs together; avoid disabling sleep, which raises energy use considerably. |
Energy use and running costs
ENERGY STAR rates this device on its low-power modes: 1.56 W in sleep and 0.08 W when switched off. If it stays plugged in and asleep around the clock, sleep mode alone uses about 13.7 kWh per year — roughly $2.32 at $0.17 per kWh.
Switching it off outside a 10-hour, 5-day work week (and letting it sleep during working hours) cuts that to about 4.55 kWh per year ($0.77).
Energy used while actively printing is not included in these figures; it depends on how many pages you produce.
