Epson SIDM Black Ribbon Cartridge LQ-690 Series

Non-Stop Commercial Printing

The Epson SIDM Black Ribbon Cartridge (C13S015610 / S015610) is a high-capacity, heavy-duty 24-pin impact printing consumable purpose-built for the Epson LQ-690 and LQ-690C flatbed dot matrix printers. Impregnated with a specialized, high-density black ink formulation across a high-tensile continuous-loop woven nylon fabric ribbon, it delivers an extraordinary output of up to 10 million characters. Engineered to meet the rigorous demands of high-volume administrative, banking, and logistical operations, it ensures letter-quality print sharpness on thick multipart carbon forms, delivery notes, passbooks, and continuous invoices. The custom-molded cassette housing provides uniform ribbon tension to eliminate twisting or jamming, while integrated ribbon lubricants continuously shield printhead needles against friction and thermal stress during rapid, heavy-duty print runs

Key Features

Massive Ten Million Character Yield

Ultra-dense ink saturation delivers up to ten million characters per cassette. The high-capacity reservoir minimizes consumable replacement frequency during extreme volume accounting and banking print cycles.

Superior Multipart Form Transfer

High-tensile fabric weave distributes exact impact forces across thick passbooks and multipart carbon sets. Deep ink penetration produces crisp, high-contrast impressions down through the final copy.

Extended Printhead Needle Shielding

Specialized liquid lubricants infused within the ink continuously coat fine 24-pin needles. Active pin lubrication suppresses frictional heat build-up and wards off premature mechanical component wear.

Reinforced Heavy-Duty Nylon

Continuous-loop fabric structure resists stretching and fraying under continuous high-speed carriage movement. Controlled ribbon tension guarantees uniform tracking without twisting or snagging inside the printer chassis.

Seamless Flatbed Printer Integration

Precision-molded cassette casing snaps directly into Epson LQ-690 and LQ-690C flatbed dot matrix printers. Custom enclosure alignment enables swift, clean cartridge exchanges that eliminate workplace downtime.
