LD Products no longer carries the Sharp AJ-C50B ink for the AJ-5030. We strive to carry the largest selection of ink and toner cartridges. Unfortunately, there are only a few AJ-5030 printers out there, and even fewer compatible or remanufactured supplies, therefore, we no longer stock these cartridges. Need a new printer?
