Factory Repairs

Comark offers a Return Material Authorization (RMA) procedure for the return of damaged or defective products for repair. All repairs, both in and out of warranty, are done at our factory in Milford, MA. Purchase Orders are required to process repairs and cover the cost of misuse, damage during shipment due to improper packaging, and incorrect setup, as well as standard repair charges for out of warranty products. You will be notified of any charges prior to execution of repairs and provided a quote with repair costs. Comark will offer repair services on products that are less than 7 years from the original ship date only. Products that are older will need to be replaced by purchasing a new product.

Repair Warranty and Advance Replacements (Comark Brand Products only):
Comark warrants its repaired products to be in good working order for a period of 90 days from the date of shipment for out of warranty repairs. Should products fail to perform properly within that period, Comark will, at its option, repair or replace the products at no cost except as set forth in our warranty. In-warranty repairs maintain their original warranty period or 90 days from the date of the repair shipment, whichever date is later. Repair warranties cover the actual repair and not necessarily the entire system.

Advance Replacement parts are available for Comark brand products only. Parts will be furnished on an exchange basis only for in-warranty product for customers in good standing. Standard credit terms apply - customers without an established account need to submit a credit application or pay with a credit card. Defective parts, once returned and repaired, become the property of Comark. Full Credit will only be applied to the Advance Replacement Invoice if all original product manuals, components and software licenses (unopened) are returned with the defective system. If the defective items are not returned to Comark within 15 days from the receipt of the replacement parts, the Advance Replacement Invoice will be considered due and payable.
Please see our Warranty Policy for additional details.
