Brand‑new original LDD23 PCB, part number 857C1059597, core control section board for Fuji Frontier 550,570,570R, LP5500, LP5700 digital minilab. Every board undergoes full‑function inspection & testing before shipment. Direct plug‑and‑play replacement for faulty original LDD23 board, fixes machine startup error, printing abnormality and related alarm codes. Reliable spare part for photo lab maintenance & repairing Fuji minilab printer.

Original brand‑new switching power PCB PN: I038401‑00 (PS1 power unit), specially designed for Noritsu QSS 32 / 35 / 37 / 38 series digital minilab photo printing machine. It provides stable 24V 9A & 5V 5A dual output for the whole minilab system. Strict quality inspection & full‑function testing before shipment. Perfect replacement when original power board burn‑out, no power output, startup failure. Reliable brand‑new spare part for photo lab daily maintenance.

The reconditioned J390947 Printer Control PCB Board is original replacement spare‑part for Noritsu QSS‑3201, QSS‑3202, QSS‑3203, QSS‑3301 and LPS‑24Pro digital minilab. As the core logic mainboard of printer unit, it handles signal communication, multi‑motor drive control, sensor acquisition and laser exposure synchronization. It fixes common PCB‑caused failures including printer communication abort, motor non‑response, random error codes, print abort and initialization failure. This board is fully reconditioned and function‑tested for stable continuous operation in commercial photo labs. Professional technician installation and machine initialization are required. Please confirm your original part number before purchase.

Brand‑new replacement Printer I/O PCB Board, Part No. J391490‑00, compatible with Noritsu QSS‑32 and QSS‑37 series digital silver‑halide minilabs. This printer input‑output interface board undertakes signal interaction between printer main control board and on‑site components: collecting sensor feedback signals, sending driving commands to solenoids, paper‑transport actuators and mechanical switches. It ensures reliable signal transmission for paper detection, paper magazine sensing, mechanical home position detection and safety interlock protection. Circuit damage caused by static electricity, voltage spike or component aging will trigger typical malfunctions: sensor mis‑reading, paper‑jam false alarm, magazine detection failure, mechanism no response, intermittent printer error codes and printing workflow abort. Replacing with brand‑new J391490‑00 I/O PCB restores normal printer signal interaction function, eliminates IO‑related faults and reduces photo lab production‑stop loss.

Brand‑new replacement main power supply board, Part No. **J391466**, designed for Noritsu QSS‑37 and QSS‑38 series digital silver‑halide minilabs. This is the core power‑supply unit for the printer section, converting input AC power into multiple groups of stable DC voltage for printer motors, solenoids, sensors and exposure modules.
