Narrative:

Someone left paper-like substance in fuel tank and this was not seen during clear to close. We were given a write-up stating 'left wing inboard stub wing fuel tank requires cleaning due to paper-like substance in tank.' upon further investigation; we found the paper-like substance was found throughout the tank and covered all 3 fuel pump intake screens. The majority of which was found on pump 1-B's screen and not all could be removed while pump still installed in tank. After removing the paper-like substance from tank; it appears to be colored and what appears to be some sort of tape. Because there is still paper-like substance on the inlet screen of fuel pump 1-B; a work order was written to remove pump 1-B for cleaning or replacement. Also work orders were written for replacement of the fuel filters for #1 and #2 engines and APU. A better clearance to close inspection before closing the tanks. This event happened in june at a maintenance base during a heavy check on aircraft X.
